cheese-bands runs source detection on full-field images in two bands and creates cheese masks from the output. cheese-bands produces the event, exposure, and mask images that are required in a user-selected energy band. Running cheese-bands is not required if only the spectral files with all counts including point sources are required, or if excluding point sources is not of interest.
Warning and requirements: cheese-bands is part of the esas package, integrated into SAS, but it is limited to work within esas data reduction scheme. This is specially true wrt the structure and names of the input files. In particular, cheese-bands assumes that another task from the package, mos-filter, or pn-filter, have been successfully run for the exposures to be used. NOTE: cheese-bands can operate on only one exposure per instrument.
