interpretLOs

Return to directory of Todd's CASA extensions

Interpret (and optionally print) the LO settings for an MS. Note: printLOs is now simply a wrapper for this function.

Usage:

au.interpretLOs(ms, parentms='', showWVR=False, showCentralFreq=False, verbose=False, 
          show=False, alsoReturnLO2=False, birdieFreq=None, birdieSpw=None)
Inputs:
  • showCentralFreq: if True, then show the mean frequency of each spw, otherwise show the frequency of the first channel
  • showWVR: include the WVR spw in the list
  • parentms: if the dataset has been split from a parent dataset, then you may also need to specify the name of the parent ms.
  • alsoReturnLO2: if True, return a second dictionary of the LO2 values
  • birdieFreq: if specified, compute the IF of this RF feature (in GHz, Hz or a string with units)
  • birdieSpw: only necessary to specify if there is more than one LO1 in the science spws

Returns:
  • a dictionary of the LO1 values (in Hz) for each spw, keyed by integer.

Example:

CASA <5>: au.interpretLOs('uid___A002_X6fdf5f_X846.ms')
