uset - sets/splices Ultracam frames

uset sets a CCD or a single window of a CCD of one Ultracam frame to its value in another. This can be used to splice together frames. For instance to make a single flat field frame from ones that are well exposed in each CCD separately.

Invocation

uset input1 input2 [coerce] output nccd nwin

Arguments

input1---First input frame.
input2---Second input frame. The windows of this frame must at least match or enclose those of the first frame.
coerce---Coerce the second input file to match the first's format or not. Not always possible: needs binning factors to be correctly related and window start positions to match up correctly.
output---Output frame. This will be the same as the first input, but with some parts replaced by data from the second input frame.
nccd---CCD number. 0 means all, but allows a particular window of each CCD to be set
nwin---Window number if only one to be set, 0 for all.
