pipeline.hifa.cli.hifa_session_refant

hifa_session_refant(vis=None, phase_threshold=None) → Results[source]

Select best reference antenna for session(s).

This task re-evaluates the reference antenna lists from all MeasurementSets within a session and combines these to select a single common reference antenna (per session) that is to be used by any subsequent pipeline stages.

Parameters:

  • vis --

    List of input MeasurementSets. Defaults to the list of MeasurementSets specified in the pipeline context.

    Example: vis=['ngc5921.ms']

  • phase_threshold --

    Threshold (in degrees) used to identify absolute phase solution outliers in caltables.

    Example: phase_threshold=0.005

Returns:

The results object for the pipeline task is returned.
