The primitive display (as reduce -r display blah.fits) runs the full addDQ on raw data. This forces a request for a BPM and a calibration association (even a download if using a server) and an attempted to align and add the illumination mask. Neither are needed. display only needs to identify the saturated pixels. It is probably just a case of calling addDQ with different defaults.
