WFCAM processing steps prepare - ingest MEFs, check, index, select, preview, process instrumental signature removal - darks, flats, curtains, cross-talk sky artefact correction - group master skys by time/ OB combine - compute shifts, interleave, stack dithers catalog - detect and parameterise objects [aperture photometry] classify - morphological classification [curve-of-growth] astrometry - astrometric calibration per detector photometry - photometric calibration per pointing [detector gain] check - examine QC, reject bad products, visual inspection
