Remove Spectral Index stuff from attenuate() function in operations_lib.py
The Spectral Index stuff in LSMTool
was introduced by @rafferty in a time where WSClean
did not yet support correcting apparent sky models to "real" sky models. Therefore there's a part in the apply_beam()
function in operations_lib.py
that basically tries to determine "apparent spectral indices". This code was neither well-tested, nor is it used often. It was decided to remove the Spectral Index stuff from LSMTool
. This MR deals with that.
Closes RAP-704
