pipeline.h.heuristics.tsysspwmap(ms, tsystable, trim=True, relax=False, tsysChanTol=1)[source]¶

Generate default spwmap for ALMA Tsys, including TDM->FDM associations Input:

ms the target MeasurementSet object tsystable the input Tsys caltable (w/ TDM Tsys measurements) trim if True (the default), return minimum-length spwmap;

otherwise the spwmap will be exhaustive and include the high-numbered (and usually irrelevant) wvr spws

relax (not yet implemented)

Output:

spw list to use in applycal spwmap parameter for the Tsys caltable

This function takes the Tsys Caltable you wish to apply to a MeasurementSet and generates a “applycal-ready” spwmap that provides the appropriate information regarding the transfer Tsys calibration from TDM spectral windows to FDM spectral windows. To execute the function:

tsysmap=tsysspwmap(vis=’my.ms’,tsystable=’mytsys.cal’)

tsysmap can then be supplied to the applycal spwmap parameter to ensure proper Tsys calibration application.
