Return to directory of Todd's CASA extensions

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.

Usage:

au.representativeFrequency(vis, verbose=True)

Inputs:

• vis: name of measurement set
• verbose: if True, then also print the min/max acceptable angular resolutions

Returns:

• Returns the value in GHz.

Examples:

CASA <4>: au.representativeFrequency('uid___A002_Xa424cc_X3ee.ms')
minAcceptableResolution = 0.649003 arcsec
maxAcceptableResolution = 0.793225 arcsec
  Out[4]: 282.45000000000005

CASA <2>: au.representativeFrequency('uid___A002_X9f9284_X1fb6.ms')
Could not find ASDM_SBSUMMARY table.  Did you not import it with asis='SBSummary'?
