Description

The shift and add process means that the counts observed in each pixel of an OSW image may have been accumulated in several different detector pixels. This task takes the OM tracking history and applies it to the map of bad pixels defined in the CCF. The result is an increase in the area of the OSW image contaminated by bad pixels. The bad pixel map produced by this task will be used by the source detection algorithms and the OMMODMAP task. The binning of the bad pixel map, and the offset of the science window, are read from the headers of the OSW image, which is an input of the task.
