VIRCAM: Association map
Calibration Plan

Within the reduction cascade, all calibration products are checked with respect to their quality and their relationship in time. This means e.g. that a master flat is generated using a quality-checked Master Dark, which is taken closest in time to the raw data for the master flat field.

All products created by QC Garching follow the reduction cascade. The reduction cascades for daytime calibration and nighttime observations (standard stars and science data) are shown below.

Schematic overview of the VIRCAM association map. Since 2017 two SCHLEGEL_MAP static calibrations are provided when downloading science frames from the archive.

The operational VIRCAM association map for the only mode IMAGING is shown here.
