2.3.2.0 vpmanager.setpbimage

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.

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.
