vpmanager.setpbimage - Function

2.3.2 Make a vp/pb from a user-supplied image

Description

Experimental: Supply an image of the E Jones elements. The format of the image is:

Shape: nx by ny by 4 complex polarizations (RR, RL, LR, LL or XX, XY, YX, YY) by 1 channel.
Direction coordinate: Az, El
Stokes coordinate: All four “stokes” parameters must be present in the sequence RR, RL, LR, LL or XX, XY, YX, YY.
Frequency: Only one channel is currently needed - frequency dependence beyond that is ignored.

If a compleximage is specified the real and imaginary images is to be left empty.

The other option is to provide the real and imaginary part of the E-Jones as seperale float images On that case one or two images may be specified - the real (must be present) and imaginary parts (optional).

Note that beamsquint must be intrinsic to the images themselves. This will be accounted for correctly by regridding of the images from Az-El to Ra-Dec according to the parallactic angle.

antnames is the Vector of names for which this response pattern apply ’*’ is for all The name has to match exactly the name of the Antennas in the ANTENNA table of the MS with which you want to use this VPManager table or object.
