VISTA/WFCAM pipelines
summit pipeline: real time DQC verified raw product to Garching
standard pipeline: instrumental signature removal, catalogue production, astrometric and photometric calibration
further processing: generate well sampled PSF, PSF and Sersic profile fitting
advanced pipeline: database driven, deep stacking and mosaicing, merging catalogues, list driven photometry, overlap calibration

Technical challenges
non-linearity calibration and measurement
cross-talk between channels and detectors
image persistence from frame-to-frame
sky level variations on short timescales
rapid variability of OH fringing
seeing variations on short timescales
possible time varying flatfield characteristics
calibration and extinction monitoring
data volume and throughput
robust automatic DQC measures
