sensitivityAdjustment

Return to directory of Todd's CASA extensions

Implements the equation in the 13/Jul/2016 comment in CAS-8534, which determines how much to increase the predicted sensitivity level coming from ia.apparentsens when the effective bandwidth of an spw channel is not equal to its physical bandwidth.

Usage:

au.sensitivityAdjustment(N=2, nchan=1, spwchan=128, window='hanning')
Inputs:
  • N: amount of online channel-averaging (1,2,4,8,16)
  • nchan: amount of offline channel-averaging (can be a floating point value)
  • spwchan: total number of channels in the spw
  • window: window function used by the correlator

Example:

CASA <116>: au.sensitivityAdjustment(2, 356, 960)
  Out[116]: 1.2642855868284442
