  1. To hide, or not to hide, that is the questionTowards common philosophy about rejecting, hiding badqual of the calibration data Good data – definition: stable in time, closely correspond to the status of the instrument; should be “scored green”, but can also be “scored red” if the reasons are understood and accepted; Reason for rejecting: to assure that only certified/good calibrations are used to be associated with science data (science ABs, the static solution of the calSelector,) and only certified/good master calibrations are ingested in the Archive; Reason for hiding: to clean the ESO Archive from bad/unusable calibration raw frames that could otherwise be picked up by future users (the dynamic solution of the calSelector); Reason for badqual: to assure that, on the calChecker level, only certified/good calibrations are considered for science association; main motivation is to alertParanal if good calibrations are missing;

  2. FOOTNOTES: Hiding of the raw frames in the Archive should be exception and not a habit. The assumption is that Paranal delivers mainly good data.
