CRIRES reference frames

The CRIRES reference frames pages offer:

  • example frames for the daily health check settings (plus selected additional settings)
  • an atlas of ThAr and N2O wavelength calibration exposures
  • S/N in flat fields.

Daily Health Check settings

The following CRIRES calibrations are measured daily independent from the settings used during the night:

  • DARKs: a set of 3 darks for DIT = 1 and DIT = 300 sec
  • FLATs: one flat-field for each for the reference wavelengths 1090.4, 3218.6, and 4092.9 nm;
    two flats with 2199.1 nm, one with the halogen lamp and one with the IR emitter
  • WAVEs: a ThAr exposure for 1090.4 nm and a N2O exposure at 4092.9 nm.
