ommodmap (ommodmap-2.26) [xmmsas_20230412_1735-21.0.0]


Description

This task corrects a given OSW image for `modulo-8' spatial fixed-pattern noise that results from the OM centroiding algorithm. If there are sufficient counts in the OSW image the mod-8 tile can be constructed and applied to the OSW. Both the mod-8 corrected OSW image and the mod-8 map are outputs of the task.

The following functionality is currently not available:

If the s/n of the OSW image is too poor (typically because the OSW image was obtained in FAST mode and is too small to provide good statistics), then an alternative IMAGE mode image that encompasses the FAST mode window is used to construct the mod-8 tile. If no such alternative image is available then the task is aborted.
