Perform polarization calibration for VLA circular feeds.

Only validated for VLA sky survey data in S-band continuum mode with 3C138 or 3C286 as polarization angle. Requires that all polarization intents are properly set during observation.

Parameters:

  • vis -- List of input visibility data.

  • Dterm_solint --

    D-terms spectral averaging.

    Example: refantignore='ea02,ea03'.

  • refantignore -- String list of antennas to ignore.

  • leakage_poltype -- poltype to use in first polcal execution - blank string means use default heuristics.

  • mbdkcross -- Run gaincal KCROSS grouped by baseband.

  • clipminmax -- Acceptable range for leakage amplitudes, values outside will be flagged.

  • refant -- A csv string of reference antenna(s). When used, disables refantignore. Example: refant = 'ea01, ea02'

  • run_setjy -- Run setjy for amplitude/flux calibrator, default set to True.

Returns:

The results object for the pipeline task is returned.
