Astrohack

This release contains a few changes to locit, plus a new method for installing astrohack in NRAO machines.
- LOCIT:
- Delay plots with the fitted delay model now display the delay model residuals.
- Improved selection of X and Y limits on delay, and sky cover plots.
- Table that contains position corrections now present station numbers and fit RMS in degrees.
- Added a method to the position_mds called export_to_parminator to export locit results to a parminator file.
- Changed formatting of values in the table that contains position corrections.
- Installation under a VENV:
- Installation script.
- CASA fringe fit and phase gain script for pre locit reduction.
- LOCIT execution script.
- post locit parminator export script
- installation instructions on the wiki
- Execution instructions on the wiki

This release contains a miscellany of minor changes and a few bug fixes.

- extract_holog:
- Corrected the time interpolation of pointing for the case in which the pointing table is sampled less frequently than the visibilities (pre 2021 VLA).
- Changed test on needing to fix the pointing table to when there are no mapping antennas rather than using a date.
- Changed the default of baseline_average_nearest parameter from 'all' to 1.
- locit:
- Fixed the case where field_ids were taken from the negative phases but assumed to be the same as the positive phases which cause an access error due to array length.
- Reference antenna is now always marked on the output table with antenna position corrections.
- The antenna position corrections table is now printed when position_mds.export_locit_fit_results is called.
- Miscellanious:
- Fixed the formatting of the API documentation in readthedocs for a few tasks where line breaks were causing a formatting breakdown.
- Updated github workflows to use V4 artefacts rather than V3 artefacts.

This release contains a series of minor improvements.

Panel:
- Amplitude cutoff based on noise maximum and threshold on excluding data.
- RMS in screw file is now always quoted in mm as well as the unit chosen.
- Antenna gain is now computed using the expected FWHM of the primary beam.

Extract_holog:
- It is now possible to exclude antennas that have bad data.

Miscelanious:
- Fixed a typo in notebooks referencing apply_mask, a defunct parameter of holog, that caused the notebooks to not complete execution.

This release contains the following changes:

- It is now possible to specify a specific amplitude cut off for any antenna and ddi combination.
- Apertures are no longer clipped to allow for the analysis of the noise outside the dish image.
- Aperture amplitude plots now display simple amplitude and noise statistics.

* New Feature:

- Added antenna surface RMS estimates before and after screw adjustments to Gain table and screw adjustment files.

* Bug fixes

The U and V axes of the aperture FITS files produced by image_mds.export_to_fits
had the wrong values, this is now fixed.

extract_holog now works with int ddi input


* Improvements
Improved resolution of the display of frequency in the file containing the screw adjustments

Improved header definition of the exported ASCII screw adjustment file

gaussian convolution is now the default gridding method in holog.

Panel fitting and correction have been optimized with execution times being 10-50% faster depending on model.

holog_obs_dict json files are no longer created as hidden files (. file name)

Decreasead overall verbosity of tasks.

* New Features

New method for image_mds file that export phase fitting results: export_phase_fit_results

New method for panel_mds file that export estimated antenna gains at multiple frequencies: export_gains_table

New model for panel fitting, flexible, based on the model of the same name found in AIPS.

inspect_holog_obs_dict now also opens the holog_obs_dict inside of holog_mds files.


* Miscelanious changes

Replaced dependency of graphviper with toolviper
