February 2015: the current content of the VISIR reference frames pages presents data taken with the old detectors (operational until May 2012). These will be replaced once new data are available.

The pre-upgrade daily Health Checks included:

  • a set of 2 dark frames for the imaging and spectroscopic detector; for the spectroscopic detector darks are taken in two instrumental setups: every day
  • a set of 6 flatfield frames for the imaging detector: every day
