receptorAngles

Return to directory of Todd's CASA extensions

Reads and summarizes the RECEPTOR_ANGLE column of the FEED table of a measurement set, as a list of angles associated with each antenna. These angles are stored in radians. If there are multiple receiver bands in a measurement set, then multiple angles will be shown. See also fixReceptorAngles.

Usage:

au.receptorAngles(vis)
Returns:
  • the median value as an array of 2 values, unless that median is [0,90] or [0,pi/2] in which case it returns None.

Example:

CASA <4>: au.receptorAngles('uid___A002_Xaa5ac2_X1f2.ms')
Antenna Receptor_angle (= converted to degrees)
 0 CM01 [-0.93462381  0.63617251] ( = [-53.55  36.45])
