This is the trending report for UVES QC parameters derived from DARK frames.
These frames are taken approximately once per month, as a set of 3 consecutive exposures of 3600 secs each. These data are de-biased and combined into a MASTER_DARK, in which the average dark level is measured (in ADU/px/hr).
These plots describe:

1. the DARK current in master DARK frames of the BLUE chip in the 1x1 binning, 225kHz, low gain readout mode
2. same for REDL chip, 1x1
3. same for REDU chip, 1x1
4. the DARK current in master DARK frames of the BLUE chip in the 2x2 binning, 50kHz, high gain readout mode
5. same for REDL chip, 2x2
6. same for REDU chip, 2x2

1. BLUE Chip: 0.4 (lg: 0.22, hg: 0.74)
2. RED CHIPL: 0.5 (lg: 0.31, hg: 0.96)
3. RED CHIPU: 1.5 (lg: 1.03, hg: 2.88)
