Add Standard Imaging summary in Section "Summary"of DRLD
You can steal the start for this from Ric's OCD draft :
" Data Processing In terms of data processing, only pre-calibrated or modelled distortions will be applied to the frames before they are combined. The secondary guiding stars will be used by the pipeline to derive the optimal spatial matching between the frames. This may be more than just a lateral shift, and could
include also rotational and plate scale corrections. In the ideal situation, it may be possible to com- bine frames ‘blindly' using only the offsets in the image headers.
Photometric calibration will, by default, be performed directly on the science images themselves, by referencing sources to catalogues (e.g. Euclid, LSST, Gaia). The alternative of using calibration fields will also be available. "
