cheese

Abstract:

This task creates "Swiss cheese" masks after running source detection on full-field images. This is a f95 rewrite of the pre-SAS-21 esas perl subtask cheese. This task runs edetect_chain, region, and makemask in a self-consistent manner for up to two bands and all three EPIC instruments. Some of the output files from cheese can be further edited or modified by the user to allow very precise control of the source removal; doing so requires the reapplication of region and makemask.
