readTcal
Return to directory of Todd's CASA extensions
Read the Tcal, Trx, Tsky, or Tsys spectrum for a specific antenna, spw and time. If the
time is not specified, it will return a dictionary of spectra keyed
by the time (in MJD seconds). The spw should be an spw number
in the measurement set that is associated with a CALIBRATE_ATMOSPHERE scan.
A conversion will be made to the spw number
in the ASDM using
asdmspwmap. If the spw is FDM, it is up to the user to find
the associated TDM spw (e.g. using tsysspwmap) and pass it in.
Usage:
au.readTcal(asdm, antenna, spw, meantime=None, spectrum='tcal', verbose=False)
- antenna: the antenna ID (string or integer, not the name)
- spw: the spw ID (string or integer)
- spectrum: 'tsys', 'trx', 'tsky', or 'tcal'
Returns:
A dictionary keyed by the MJD in seconds, with values equal to a list of
arrays (one per polarization) each with N channels.
Example:
CASA <6>: au.readTcal('uid___A002_X723a9d_X20e',0,19)
