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
