Get the representative frequency from the ASDM_SBSUMMARY table of a measurement set, if it has been imported with asis. It also displays the min/max acceptable angular resolutions. See also representativeFrequencyFromASDM.


au.representativeFrequency(vis, verbose=True)
  • vis: name of measurement set
  • verbose: if True, then also print the min/max acceptable angular resolutions
  • Returns the value in GHz.


CASA <4>: au.representativeFrequency('')
minAcceptableResolution = 0.649003 arcsec
maxAcceptableResolution = 0.793225 arcsec
  Out[4]: 282.45000000000005

CASA <2>: au.representativeFrequency('')
Could not find ASDM_SBSUMMARY table.  Did you not import it with asis='SBSummary'?
