Fill in the photometry keywords PHOTFLAM, PHOTZPT, PHOTPLAM, and PHOTBW with values selected from the reference table line that matches the PHOTMODE keyword. The PHOTMODE keyword itself is constructed during CALWFP processing from values of several other keywords which specify the camera, chip, and filter(s) used during the observation. The name of the photometry reference table must be provided in the keyword PHOTTAB if this option is selected.
