Try-except the final closure of the dome after a calibration.
Ensure that the observing loop and calibrations are stopped if the dome is closed outside of the Overwatcher.
Add flag --close-dome to lvm.overwatcher disable to close the dome after disabling the Overwatcher. Requires using --now.

🏷️ Changed/removed¶

Prevent automatic dome closure by the Overwatcher if it is disabled and the alert is not critical (wind, humidity, etc.)
Removed the reset_lockout argument for the shutdown recipe since it’s not required to allow the dome to move.
Do not close the dome during daytime if the Overwatcher is disabled.
Remove dome lockout after unsafe conditions. It may be reimplemented differently in the future.

🔧 Fixed¶

Fixed a regression that would mark a retrying calibration as done.

Improve handling of errors during the focusing sequence in the Overwatcher.
Clarify the behaviour of min_time_between_repeat_notifications in the NotifierMixIn class.

🔧 Fixed¶

Fixed a race condition that could prevent the shutdown of the dome when twilight was reached. Instead of commanding a shutdown inside the Overwatcher observing loop (which cancels the same task that is commanding it), the loop will now complete normally and the main Overwatcher task will command the shutdown.

1.5.1 - January 15, 2025¶

🔧 Fixed¶

Fixed an issue setting the initial calibrations schedule SJD.
Prevent a failed notification to raise an error by default.

Fixed an issue that would crash the alerts task when checking the internet connection if the request timed out.
Ensure that CalibrationsOverwatcher.reset() is called.

1.4.0 - January 1, 2025¶

🚀 New¶

#45 Added a health module that emits a heartbeat to lvmbeat and monitors actor health by ping, restarting them if found unresponsive. The pre-observing task now also perform that check.

✨ Improved¶

#44 RORR RID-019: disables the Overwatcher if rain is detected and requires a human to re-enable it when conditions are safe.
#46 RORR RID-017: treat lost connectivity to the internet or LCO as an unsafe condition and close.
Create the night log during the pre-observing task.
The gort overwatcher command now accepts a --verbose flat that allow to set the verbosity level of the messages output to the console while the Overwatcher is running (the file log level is always DEBUG). The default level is now WARNING.

🏷️ Changed¶

Removed the pubsub module and use lvmopstools instead.
Rename and expose RemoteCommand._run_command() to RemoteCommand.run().

🔧 Fixed¶

Do not run the post-exposure checks when cancelling the loop.
Fix call to /notifications/create for new API version.

1.3.0 - November 29, 2024¶

🚀 New¶

#39 Implement transparency monitoring.
Add observer schedule-focus-sweep command to Overwatcher actor to schedule a focus sweep before the next tile.

✨ Improved¶

#40 Slight internal restructuring of the core classes Gort, GortClient, device and remote actor classes. The main goal was to avoid any other part of the library knowing about GortClient, which does not include anything not related to its AMQP client function any more.
Use Retrier from lvmopstools to handle remote command retries.
Prevent repeat notifications with the same message.
Add retries to NPS commands.

🔧 Fixed¶

Prevent trying to observe while a calibration is ongoing even if it’s night.
Add max_start_time to bias_sequence to prevent if from running after twilight.

1.2.1 - November 20, 2024¶

✨ Improved¶

#41 Only emit an error event when the exception is actually raised.
Report if the observer is focusing or troubleshooting.
Stop MoTAN devices before a new move and improve error reporting.
Allow fibre selector to rehome if a move fails.

🔧 Fixed¶

Fix a bug that would cause the calibration module to always add a night log comment indicating that the calibration had failed.
Prevent the K-mirror from being homed and parked at the same time.

1.2.0 - November 17, 2024¶

🚀 New¶

Overwatcher now reports error events via notifications. If the error happens while a tile is being observed, a comment in the night log is added.

✨ Improved¶

Roll over the GORT log when the SJD changes.
Improve the logic handling how the Overwatcher observer decides when to open or close the dome near evening or morning twilight.
Run a clean-up first in pre-observing in case the spectrographs are not in a good state.
Run some pre-observing checks before calling each GortObserver.observe_tile() in the ObserverOverwatcher. Currently only checks if the spectrographs have an error state and resets them.
Handle SPECTROGRAPH_NOT_IDLE errors in the troubleshooter.
Disable the Overwatcher and cancel observations if the dome fails to move.
Add retries for safe enclosure operations.

🔧 Fixed¶

Fixed a bug that would prevent a new SJD to trigger an update of the ephemeris and calibrations.
Fix a bug that would leave the Overwatcher in cancelling mode if start_observing failed.

1.1.2 - November 11, 2024¶

✨ Improved¶

Take AG darks during the pre-observing task.
Add retry_without_parking option to the shutdown recipe.
Emit events for dome opening and closing and report them as notifications.
Modified emergency_shutdown() to close the dome if the shutdown recipe fails.

🔧 Fixed¶

Prevent the calibrations module from trying to close the dome when a calibration is retrying.
Prevent a case in which failing to park the telescopes could have caused the dome to not be closed even if retry_without_parking was set to True.

1.1.1 - November 10, 2024¶

🚀 New¶

#38 Add a post-observing daily task that runs 15 minutes after morning twilight and will do a few check (make sure the dome is closed, park the telescopes, etc.) and retry safe calibrations that failed during the normal sequence.

✨ Improved¶

Add a comment to the night log when a calibration fails.
Do not start exposure if we are within 10 minutes of twilight.

🔧 Fixed¶

Prevent the Overwatcher observer from opening the dome while calibrations are ongoing.
Fixed a bug in the twilight flats recipe related to the extra exposures.

⚙️ Engineering¶

Use API to send notifications.

1.1.0 - November 7, 2024¶

🔥 Breaking change¶

GortObserver.observe_tile now default to async_readout=False. This will block until the exposure is done, which is a more natural behaviour for an external user that is not trying to over-optimise things. The code that uses observe_tile in GORT (Gort.observe() and ObserverOverwatcher.observe_loop_task()) have been updated to explicitly use async_readout=True.

🚀 New¶

#37 Basic implementation of the Troubleshooter class for the Overwatcher. Currently only very broad troubleshooting checks and recipes are implemented.

🏷️ Changed¶

Removed morning twilight flats.

🔧 Fixed¶

Temporary fix in the cleanup recipe for a bug in lvmscp caused by a quick reset after reading out a pending exposure.

⚙️ Engineering¶

Added a very basic test to confirm the Overwatcher can be initialised.

1.0.2 - November 6, 2024¶

🚀 New¶

#34 Adds a safety module to the Overwatcher that will monitor the alerts independently and close the dome at a very low level if the main task fails to do it after 5 minutes.

✨ Improved¶

#35 Refactor dither observing to allow finer control of when to reacquire a tile and when to keep observing and adjust the science telescope dither position.
#36 Modity the evening twilight recipe to continue cycling the standards mask and taking flats until the exposure time reaches 100s.
GORT will fail to initialise if the Overwatcher is running. This can be overridden by passing override_overwatcher=True to the Gort constructor or --override-overwatcher in the CLI.
Rearranged the Overwatcher helpers and make the pre- and post-observing scripts recipes.
Added a framework for run daily tasks and a pre-observing task.
Add option to disable the overwatcher to the shutdown recipe.

1.0.1 - October 30, 2024¶

✨ Improved¶

Overwatcher: cancel the current cancellation if conditions are unsafe.
Overwatcher: lock the dome for 30 minutes if it’s closed due to unsafe conditions.
Always reset the spectrographs before an exposure. Add some checks to ensure the shutters are closed during a cleanup.

🏷️ Changed¶

Overwatcher: rename allow dome calibrations to allow calibrations, which enabled/disables all calibration (not only in-dome calibrations).

🔧 Fixes¶

Overwatcher: fixes to daytime logic.
Add the current GORT version to the Overwatcher actor.
Set the correct dither position in GortObserver.

1.0.0 - October 28, 2024¶

🚀 New¶

#32 Initial complete implementation of the overwatcher.

🔧 Fixed¶

#33 Fixed an issue in which the first standard would not be reacquired during dithered observations. Also forces a rehoming of the fibre selector mask before each observation.

1.0.0b1 - July 9, 2024¶

🔥 Deprecated¶

Removed the websocket code and CLI. All this functionality is now part of lvmapi.

✨ Improved¶

Wait for previous exposure to finish reading out in Observer.expose(). While this was already happening when calling Exposure.expose(), we are now blocking until the exposure finishes a bit earlier which prevents the standard loop to begin too early.
Upgraded to polars 1.0.0.

0.12.0 - July 8, 2024¶

🚀 New¶

Replace all instances of Pandas with Polars.

✨ Improved¶

In Gort.observe(), retry after a wait period if the scheduler cannot find a valid tile to observe.
Output a message after the shutdown recipe instructing observers to check the dome and confirm it’s fully closed.

🔧 Fixed¶

Manually refresh the progress bar only once a second, and only after an update. Hopefully this helps with the event loop getting sluggish after a while.
Turn off spectrograph room lights on startup.

⚙️ Engineering¶

Format code using ruff and updated dependencies and workflows.

0.11.0 - March 29, 2024¶

🚀 New¶

#23 Added observer calibration scripts as recipes quick_cals, bias_sequence, and twilight_flats.

🔧 Fixed¶

Fixed a serious issue in which if the slew fails, the retry did not send the PA and it would default to PA=0.
After the initial slew, subsequent slews of the spec telescope do not check for whether the enclosure state is remote.

0.10.0 - February 7, 2024¶

🚀 New¶

#20 Added GuiderSet.monitor() which can be used to guide at zenith with low cadence and monitor transparency and FWHM while conditions are bad.

✨ Improved¶

#19 Improvemts to focusing. After a focus sweep, the focus is adjusted based on the delta temperature before each exposure.
#21 Added GuiderMonitor which replaces build_guider_reply_list. All Pandas dataframes now use pyarrow dtypes, and some deprecations and errors have been addressed.

0.9.0 - January 31, 2024¶

🚀 New¶

Tile standard coordinates can now be defined as a list of Gaia DR3 source IDs. If the standard coordinates is a single integer, it will be assumed to be a source ID and the coordinates will be retrieved from the database.
Added code for telescope pointing models.

✨ Improved¶

Break out of `Gort.observe()`` on keyboard interrupt
Added utilities_room light to enclosure.
Update astropy to 6.0.0 and avoid it requiring to download orientation data from the internet.

🔧 Fixed¶

Fixed exposure loop not restarting after a keyboard interrupt.

0.8.0 - January 13, 2024¶

🚀 New¶

#13 Adds a signal handler for SIGINT and SIGTERM. When GortObserver is running and an interrupt is received the signal handler will run the cleanup routine.
Added spectrograph_room light to enclosure.

✨ Improved¶

SpectrographSet.reset now accepts full=True which performs additional checks and opens/closes the shutter and hartmann doors as needed. reset with full=True is run automatically during the cleanup recipe.
The GORT websocket now uses the CLU model for lvmecp instead of asking the PLC to report its status on each call to WebsocketServer.enclosure_status().

0.7.1 - December 20, 2023¶

✨ Improved¶

#14 Turn off dome lights as part of the startup and cleanup recipes.
Use `lvmnps all-off`` to turn off all lamps faster.

🏷️ Changed¶

Disable marking tiles as bad on error for now. This could cause confusion if an exposure failed and the tile was marked bad, but then the images were recovered using lockfiles.
Skip the calibration sequence on startup by default.

0.7.0 - November 24, 2023¶

🚀 New¶

Added selfie position.

✨ Improved¶

Added NPS devices for telescopes and MOCON.
Added spectrograph exposure and enclosure timeouts.
Support exposing only some spectrographs.
Verify the number of files writtent to disk by the spectrographs and their MD5s.
Mark exposure bad in post-readout if it fails.

🏷️ Changed¶

Relaxed spec and sky telescope guiding tolerances to 3 arcsec.

🔧 Fixed¶

Updated NPS to handle lvmnps 1.0.0 (including upgrade to unclick 0.1.0).

0.6.2 - November 4, 2023¶

✨ Improved¶

File logger logs to logging.path (defaults to /data/logs/lvmgort/<SJD>.log).

🏷️ Changed¶

Disable guider corrections for spec telescope after acquisition. This prevents field rotation affecting the exposure at the cost of tracking error.
Pass -PA to the guider due to different handiness for PA between the guider and the tiling database.

🔧 Fixed¶

Fixed a bug in the recording of the standards acquisition and exposure times.

0.6.1 - September 28, 2023¶

✨ Improved¶

Pass force to _prepare_telescopes().

🏷️ Changed¶

Do not run cleanup after each iteration in Gort.observe()
Set stop_degs_before.sci to 1.5.

0.6.0 - September 14, 2023¶

🚀 New¶

#11 Support asynchronous readout during GortObserved-enabled observations and implement dithering:
- Remove calls to lvmguider stop --now. The new stop command always cancels the guider task.
- Added pre-readout hook for Exposure.
- Allow GortObserver to read out an exposure asynchronously.
- Gort.observe_tile() will by default read the last exposure asynchronously to allow for the next slew and acquisition to happen during readout.
- Added a context manager GortObserver.register_overhead() that measured the elapsed time in different parts of the slew and acquisition process and records the values to the database.
- The dither positions associated with a Tile are now a list of positions that the scheduler wants us to observe. Gort.observe_tile() will try to observe all dither positions without stopping the guider.
- Added Gort.observe() with a simple loop for observing tiles.
Add dither information to Tile and support exposing multiple dither positions in the same observation.

✨ Improved¶

Pass the observed sky and standard pks to the scheduler during registration.
The K-mirror offset angle is now wrapped between -180 and 180 degrees. Hopefully this prevents some cases in which offsets angles very close to 360 degrees cause the K-mirror to fail because of a software limit.

🔧 Fixed¶

Fixed deprecations in Pandas fillna() with method='bfill'.

0.5.0 - September 12, 2023¶

🚀 New¶

Added support for telescope enclosure lights.

✨ Improved¶

#10 GortObserver.slew() and the standard iteration task now calculate the adjusted target coordinates for the spec telescope so that the slew puts the star on top of the desired fibre to be observed. Most of this relies on code copied from lvmtipo used to calculate the field angle through the siderostat.
SkyCoordinates now accepts a name attribute that is passed to the SKYENAME and SKYWNAME header keywords.
IFU PA angles passed to the headers.
Pass exposure time when registering an exposure.
Support new outputs from lvmguider 0.4.0b1.
Get actor versions on init.
Support guiding in PA (disabled for now).
Reconnect AGs during startup recipe.
Add tile_id as `OBJECT`` if no object string user-defined.

🏷️ Changed¶

Set GR{telescope}FR{0|N} with the range of guider frames in which we were guiding (as opposed to the entire guide loop including acquisition frames).
Changed default guide tolerance to 1 arcsec.

🔧 Fixed¶

Fixed some additional issues with the exception hooks that cause a recursion loop in IPython in some cases.
Fixed a bug that would accumulate the range of guider frames for an spectrograph exposure if GortObserver.expose() was called multiple times.
Fixed a slicing issue with newer versions of Pandas.
Fixed a bug that caused the exposure flavour not being passed to the headers.
Deal with cases when the scheduler cannot find a good tile to observe.

0.4.0 - August 26, 2023¶

🚀 New¶

Guider frames for each telescope taken during an exposure are added to the spectrograph headers.
Standards observed are added to the spectrograph headers. The standard information can be accessed as GortObserver.standards.
Added a cleanup recipe.
Added exposure frame to the progress bar.
Add PA parameter to tiles and propagate it to the k-mirror slew commands.
Use rich tracebacks. This can be disabled by calling Gort with use_rich_output=False. Tracebacks generated in an interactive IPython session are now saved to the file log.
Log Gort output to a temporary file by default. Gort can also be called with an argument log_file_path to indicate where to save the log, or with log_file_path=False to disable logging. The current file log path can be retrieved as Gort.get_log_path().

✨ Improved¶

#9 Refactoring of Exposure and SpectrographSet.expose(). Most of the code in the latter has been moved to the former. Added a system of hooks for the exposure process. For now, only a pre-readout hook that is called with the header before the exposure is read.
Concurrently stop spec guiding and reslew.
Pass seg_time and seg_min_num to slewStart.
The code used to build the spectrograph header has been cleaned up and consolidated in GortObserver.

🔧 Fixed¶

Explicitely define site coordinates to avoid astropy needing to download files.

0.3.0 - August 14, 2023¶

🚀 New¶

#5 Add option to restart deployments associated with a device set as GortDeviceSet.restart().

#8 Added framework for recipes along recipes for startup, shutdown, and calibration.
Add TelescopeSet.restart_lvmtan() to restart Twice-As-Nice controller.
TAN devices will timeout when homing or moving.
Add pointing information to the exposure.
Add TelemetrySet and Telemetry devices.
Use the focus-temperature relationship to determine the initial guess for focusing.

✨ Improved¶

Stop the guiders with now=True after 60 seconds.
The object keyword values is set as an attribute in Exposure and shown in the __repr__.
Coordinates.set_mf_pixel() is now available for all coordinates.
Allow to wait only for some telescopes to converge guiding.
Check if telescopes are already parked before opening/closing the dome.
Report summary of best focus in focus() command as INFO level.
Print last guider measurement before removing NaNs.
Better control of which TAN devices to home during Telescope.home() or TelescopeSet.home(). The previous home_subdevices argument has been replaced by home_kms, home_telescopes, home_focusers, and home_fibsel.
Restore previous focuser positions after homing.
Allow multiple exposures in GortObserver.expose()
Focus initial guesses are now included in the configuration. If Gort.guiders.focus() is called without a guess, the configuration values are used. The guess can now also be a dictionary of telescope name to guess value.
set_mf_pixel() can now be used with all coordinates.
Better logging of remote actor command warnings and errors.
Spec telescope will now slew to coordinates such that the target falls on the selected fibre.
Check if TAN devices are reachable.
Improvements to the documentation.

🏷️ Changed¶

Removed the options min_skies and require_spec for GortObserver.acquire() and Gort.observe_tile(). If no skies or standards are defined a warning is issued but the code will not fail.

⚙️ Engineering¶

Lint using ruff.
Improve style of the documentation.
Move Exposure to its own file.

0.2.2 - July 23, 2023¶

Fixed progress bar being affected by stdout and logs by setting the same rich Console object for logs and progress bars.
Fixed accessing the configuration from an Exposure object.

0.2.1 - July 19, 2023¶

✨ Improved¶

SpectrographSet.expose() now accepts a count parameters to expose multiple frames.
The parameter flavour for SpectrographSet.expose() is not explicitely exposed and documented.
SpectrographSet.calibrate() accepts a slew_telescopes parameters. Whether the telescopes are slewed is also determined by the type of calibrations to take.
Various improvements to the calibration schema. flavour, warmup, and the fibsel parameters now have defaults in the configuration file to which the calibration routine will revert to. If fibsel: true, a default mask iteration will be performed. Both darks and lamps now accept exposure_time which can be a float or a list of floats.

🏷️ Changed¶

SpectrographSet.calibrate() does not park the telescope by default.

⚙️ Engineering¶

Progress bars are now transient.

0.2.0 - July 18, 2023¶

🚀 New¶

Added support for spectrograph IEBs.
