... As modern observatories evolve to production units delivering data products and calibrated scientific data to the end users, new challenges arise in assessing the quality of data products. ... Taking the analogy of speed control on a motorway we can describe the system as a device (radar) collecting measurements of the system performance (passing cars). ... One of the direct applications of quality control is the verification of instrument performance based on the analysis of calibration exposures. ...
