    COMMENT STR  This HDU applies to all detections that have been analyzed
    COMMENT STR  with the IPP alternative PSF fitting procedure. 
    COMMENT STR  Note that the IPP_IDET must be unique within a file so as
    COMMENT STR  to allow matching up sources between the PSF matching and
    COMMENT STR  either the alternative PSF fits for P2, P4S, and P4D
    COMMENT STR  detections or the extended source fits to the
    COMMENT STR  Image Stack/Cumulative Sky detections.
