Data editing is performed according to the Detector and Spectral Masks specified by the sequence. Detector masks are applied prior to spectral masks. The detector mask is applied to combine the data in the spatial domain. Depending on the mask selected, data from different detectors are combined (added). This computation is done in-place, with the data from higher numbered spectral buffers being added into the lower numbered buffers. After application of the detector mask one or more spectral buffers will contain data, while one or more buffers will be empty. The detectors make up an array three detectors wide by two detectors tall. Detectors are numbered from left to right across the array, starting with 1 in the upper left, ending with 6 in the lower right. There are eight detector masks. Mask 0 no data Mask 1 all detectors co-added Mask 2 no data detectors 1,3,4,6; detectors 2 and 5 co-added Mask 3 no data detectors 1,3,4,6; detector 2; detector 5 Mask 4 detectors 1 and 3 co-added; detectors 2 and 5 co-added; detectors 4 and 6 co-added Mask 5 detectors 1 and 4 co-added; detectors 2 and 5 co-added; detectors 3 and 6 co-added Mask 6 detectors 1 and 4 co-added; detector 2; detector 5; detectors 3 and 6 co-added Mask 7 data from all detectors - no co-adding
