CRIRES: Flat field quality
| Flat flux level
| Flat flux level YJHK band
| Flat flux level LM band
QC1 database (advanced users):
Lamp flats are taken daily, as part of the calibration plan. Flats in
specific setups: INS.WLEN.ID=Y1029, J1232, H1559, K2217, L3377, M4266
are taken every day as health checks. Frames in other setups are only
obtained when they are triggered by settings of science data observed
during the night.
Information about the Quality Control performed utilizing lamp flat
frames of the instrument BEFORE the upgrade (before 2021-09)
can be found here.
LAMP FLAT flux level
||QC1 database: table, name
| QC.FLAT.FLUX || criresp_flat..flat_flux ||mean flux of the 1st input RAW frame per DIT (level/DIT) ||HC|| || [docuSys coming] |
|*Class: KPI - instrument performance; HC - instrument health; CAL - calibration quality; ENG - engineering parameter|
**There might be more than one.
The flux level per DIT [ADU/s] and RMS [ADU] for
selected INS.WLEN.ID are monitored.
Scoring&thresholds LAMP FLAT flux level
The thresholds are set to ensure optimal flux on the detectors and to
warn about malfunction of the lamp.
