Apply detapering function #9

Closed bennahugo closed 10 years ago

bennahugo commented 10 years ago

Currently missing this step - forgot to bring this up at the meeting today. This is the ("divide by F^-1(C) term" described in most literature).

Yeah, it's called detapering, since the convolution induces a taper by F(C). Here's an implementation of same for the degridder: https://github.com/ska-sa/meqtrees-timba/blob/master/MeqNodes/src/UVDetaper.cc
