Full Changelog: v0.3.0...v0.3.1

Version 0.3.0

This version adds a new freq_edge_array parameter for sub-band spectral type objects to store the the top and bottom frequency of each subband, which will become required for sub-band objects starting in version 0.5.

The optional dependency lunarsky is now required to be at least version 0.2.1.

Some code that has been marked for deprecation for two major versions was removed.

Full details below and in our changelog.

Full Changelog: v0.2.0...v0.3.0

Version 0.2.0

This version adds many new features including:

• Support for all coordinate frames supported by astropy. This is achieved via a new skycoord attribute on on point objects and the new hpx_frame attribute on healpix objects to carry the full frame information. This includes support for more frames for the various read and write methods.
• The frame_coherency (previously called ra_dec_coherency) are no longer calculated from the Stokes array on SkyModel initialization, a significant memory savings. A new method, calc_frame_coherency, can be called to calculate them and optionally store them on the object.

There are some new dependency version restrictions:

• pyuvdata >= 2.2.10
• astropy >= 5.2
• python >= 3.8

There are also a number of new deprecations and some code that has been marked for deprecation for two major versions was removed.

Full Changelog: v0.1.3...v0.2.0

Version 0.1.3

This version adds many new features including:

• The lat_range, lon_range, min_brightness, max_brightness and brightness_freq_range keywords to the SkyModel.select method.
• The SkyModel.assign_to_healpix method to assign point component objects to a healpix grid (using the nearest neighbor approach).
• The nan_handling keyword to the SkyModel.at_frequencies method to control how NaNs in the stokes array on subband objects are handled during interpolation.
• The SkyModel.calculate_rise_set_lsts and the SkyModel. cut_nonrising methods.

Also, the ra and dec are no longer required parameters on healpix objects (since that information is encoded in the hpx_inds parameter). The new SkyModel.get_lon_lat method can be used to get the lat/lon values for any sky type (calculated from the hpx_inds parameter on healpix type skies).

Full changes detailed below and in our changelog:
