v0.5.7

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.
