GENERAL INFORMATION

These pages contain information about CRIRES Quality Control parameters and trending plots.

CRIRES calibration data are pipeline-processed to create calibration products. The quality of the products is measured by QC1 parameters. All QC1 parameters are measured on calibration products using the pipeline and are stored in a database. Their evolution with time is evaluated by the trending process. All currently available trending plots can be accessed here or via the links above.

INSTRUMENT PROPERTIES TRENDED

The following properties of CRIRES instrument components are trended:

detector

dark current and read-out noise
detector non-linearity

spectrograph

stability of wavelength solution
positioning of pre-disperser and grating
stability of blaze function (flat-fields)

lamps

stability of halogen lamp (flat-fields)

overall performance

system throughput and efficiency
image quality in science frames (until September 2011)
