Swath-Dependent Data Files

Default template files have been created that specify the spatial pixel numbers to be avoided in the Pass 1 background extraction for each camera and for all source types (point, extended, and noncontinuum) sources. The file also includes values for nc, nf, and nd of the IOR. Initially, the list of spatial positions to be avoided includes only the starting and ending values and the echelle order positions, but this is modified for a particular image in the initial Data Screening step from the Nu flags determined in RAW_SCREEN.
