Method
The program uses the first input datafile to define the output
datafile in terms of its pixel size and orientation to North.
The datafiles to be mosaiced with this one are given offsets from
the first one in pixels, either by user input or calculation using
astrometry data in the datafiles. The images are then overlayed to
produce a (generally larger) output image. Where the input images
overlap and two or more input pixels are used to make up one output
pixel, the output is averaged by default. To just add up pixel
contributions without averaging, specify 'AVERAGE=N' on the command
line.
