GORT 1.2.0

🚀 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.

GORT 1.1.2

✨ 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.

GORT 1.1.1

🚀 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.

GORT 1.1.0

🔥 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.

GORT 1.0.2

🚀 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.

GORT 1.0.1

✨ 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.

GORT 1.0.0

🚀 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.

GORT 1.0.0b1

🔥 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.

GORT 0.12.0

🚀 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.

GORT 0.11.0

🚀 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.
