Lvmguider

✨ Improved

* Added `AIRMASS` and `GUIDERV` keywords to co-add FITS files and data frames.

🚀 New

* Added `RA`, `DEC`, `FWHM`, `ISFSWEEP` to the `PROC` headers, `FrameData`, and `lvmops.agcam_frame`. All AG frames are now loaded to the database, not only those associated with an exposure.
* `Focuser` now uses a temperature model to estimate the initial best focus.
* Added `adjust-focus` and `focus-info` commands. If a focus sweep has been previously executed, `adjust-focus` can be used to adjust the focuser position based on the delta temperature between the bench temperature during the focus sweep and the current temperature.

✨ Improved

* Use inverse standard deviation as weights for the focus spline fit.
* `Focuser` now has an option to require the best resulting focus to be in the range of focuser positions tested or it will automatically repeat the focus sweep with a larger step size.

✨ Improved

* Upgraded `astropy` to 6.0.0. The docker image now tries (but continues if it fails) to update the `astropy-iers-data` package before running the actor and internally `lvmguider` should never try to download IERS data over the internet.

🔧 Fixed

* Fixed `pandas` deprecation in `lvmguider.extraction`.

🔧 Fixed

* Actually import the `corrections` command.
* Use WCS to determine `RAMEAS`, `DECMEAS`, `PAMEAS` in co-added images.
* Wrap `offset_pa` in the -180 to 180 range.

In addition to the changes listed under `0.4.0b2`, this version provides:

🚀 New

* [8](https://github.com/sdss/lvmguider/pull/8) Added `corrections` command.

🔧 Fixed

* Reported FWHM were actually Gaussian sigmas. This has not been fixed.
* Improved matching of extracted sources with Gaia DR3.

In addition to the changes listed under `0.4.0b1`, this version provides:

🚀 New

* [7](https://github.com/sdss/lvmguider/pull/7) `stop` command now cancels the guider task for faster performance.

✨ Improved

* If a single camera fails to match with Gaia during guiding, retry that camera using astrometry.net.
* Use 25% percentile to calculate the FWHM.

🔧 Fixed

* The co-add file watcher seemed to skip files. Apparently this happens because some events are detected as a file being moved (from a temporary file to the final `.fits.gz` file) instead of a file creation. This version handles both kinds of events.
* Various fixes for the co-added code when dealing with missing data.
