getLOs

Return to directory of Todd's CASA extensions

Reads the LO information from an ms's ASDM_RECEIVER table. It returns a list of four lists: [freqLO,band,spws,names], where freqLO is in units of Hz. The logic for converting this raw list into a sensible association with the correct spw numbers is in printLOs, which is now simply a wrapper for interpretLOs. See also getLOsFromASDM.

Usage:

au.getLOs(inputMs, verbose=True)

Example:

CASA <8>: au.getLOs('uid___A002_X6fa591_X49b.ms')
