for a polarization observation

Proceed as for a single pointing observation with AOT CAM01 for the overheads of the selected OPERATIONS.

Since the array is read continuously, and without synchronization with the drive mechanism of the entrance wheel, one exposure is lost at the beginning and at the end of the measurement on each position of the wheel, this adds an overhead of at each position, or a total of:

The time needed to turn the filter wheel between two positions can be accounted for by the extra exposures added above.
