pipeline.hifa.cli.hifa_polcalflag

hifa_polcalflag(vis=None, examineCrossPolSum=None) → ResultsList[Results][source]

Flag polarization calibrators.

This task flags corrected visibility outliers in the polarization calibrator data using the hif_correctedampflag heuristics.

Parameters:

  • vis --

    The list of input MeasurementSets. Defaults to the list of MeasurementSets specified in the hifa_importdata task. '': use all MeasurementSets in the context

    Examples: 'ngc5921.ms', ['ngc5921a.ms', ngc5921b.ms', 'ngc5921c.ms']

  • examineCrossPolSum -- Whether to examine the XY+YX sum for multi-scan full-polarization data. Defaults to False, so only XX+YY is evaluated because the cross-pol sum can be non-flat when Stokes I is stable.

Returns:

The results object for the pipeline task is returned.
