Simulate the exposure map of a pointing pattern
Synopsis
astscript-pointing-simulate positions-cat.fits --center=1.23,4.56 --width=2,2 --img=image.fits [OPTIONS]
Description
Given a set of dithering positions ('positions-cat.fits' in the example above), and an image ('image.fits' which can be from any part of the sky, only its distortion and orientation are important), build the exposure map of the output stack after applying that dither (where each pixel contains the number of exposures that were used in it). The field of the final stack can be set with the '--center' and '--width' options.
