Slewing between two points of a raster is performed by the satellite in a rather slow motion. The time needed for this slew is defined in the ISO Observer's Manual.
Since the array is read continuously, and without synchronization with the satellite operation, one exposure is lost at the beginning and at the end of each pointing of a raster, this adds an overhead of at each pointing, or a total of for the raster. This overhead can be very significant if is small.
There is also the overheads for the DRK, CAL and CLN OPERATIONS when they have been selected.
