Two coordinate conversions are required to perform the operation:
- From detector coordinates (DETX, DETY), present
in the event list, to the angles used by
CAL_getEffectiveArea or CAL_getFilterTransmission.
This is done by first converting into mm (using the pixel size
in the TCDLT keywords and the focal length from
CAL_getMiscellaneousData), then into angles
- From angles (0,0 at the center of the field of view) into CCD
coordinates (RAWX, RAWY), used by
This is done by calling in sequence CAL_telCoordToCamCoord2,
CAL_camCoord2ToCamCoord1 and CAL_camCoord1ToChipCoord.
