Latest CASA Release: 6.6*
• Mac ARM: CASA builds for Mac ARM are now available (but do not include the Viewer). • CASA config: addition of a new casaconfig package to handle configuration settings. • Google Colab: pip-wheels for Python 3.10 (Google Colab) are now available. • polfromgain: new parameter minpacov to specify minimum parallactic coverage threshold. • tclean: new mtmfs-via-cube imaging mode (specmode='mvc') with accurate wideband primary beam correction. • getephemtable: posrefsys keyword changed to ICRS; support non-alphanumeric characters. • setjy: usescratch defaults to True; False no longer allowed with Butler-JPL-Horizons. • fixplanets: removed functionality to attach JPL-Horizons ephemeris data in MIME format (use getephemtable instead). • getephemtable: new task to retrieve JPL-Horizons ephemeris data. • getcalmodvla: new task to to retrieve flux calibrator brightness distributions and create component lists. • gencal: new parameter ant_pos_time to limit period for which antenna position corrections are included. • tclean: algorithmic improvements to the ASP deconvolver for large spread of spatial scales. • tclean/sdintimaging: now checks for mismatches in column states when given multiple input MSs. • tclean/sdintimaging: now sorts input list of MSes in chronological order. • tec_maps: now consistent with new file-naming convention on remote CDDIS server. • simulator: simutil now performs case sensitive comparisons for 'known observatories'. • plotms: correlation selection now supports standard Stokes parameters and polarization quantities. • Installation: test script added to test the CASA installation. • defintent: new task to modify the scan intents of a measurement set. • sdimaging: new parameter convertfirst, to reduce the number of direction conversions. • deconvolve: mtmfs enabled as an algorithm option. • tclean/deconvolve: return dictionaries added for niter=0 calls. • image tool: fitsheader function added to return FITS header as Python dictionary. • plotms: parameter colorizeoverlay added to better specify overlay colors. • plotms: better specifies values in the legend when coloraxis is set. • Multiple MS input: clarifications added to the CASA logger on how CASA handles input of multiple MSs. • Telemetry/crash reporter: functionality deprecated.
