This plot
This is the trending report for UVES gain QC parameter derived from
Detector-Monitoring frames.
These frames are taken approximately once per month, as a set of 25
consecutive exposures, 5 BIAS frames and 10 pairs of FLATs of varying
exposure time and thus various signal level designed to sample the
full dynamic range of the detector.
These plots describe:
- the measured GAIN of the BLUE chip in the 1x1 binning, 225kHz, low gain readout mode
- the measured GAIN of the LOWER RED chip in the 1x1 binning, 225kHz, low gain readout mode
- the measured GAIN of the UPPER RED chip in the 1x1 binning, 225kHz, low gain readout mode
- the measured GAIN of the BLUE chip in the 2x2 binning, 50kHz, high gain readout mode
- the measured GAIN of the LOWER RED chip in the 2x2 binning, 50kHz, high gain readout mode
- the measured GAIN of the UPPER RED chip in the 2x2 binning, 50kHz, high gain readout mode
From user manuals in e-/ADU (ADU/e-):
- BLUE Chip low gain: 1.84 (0.54)
- RED CHIPL low gain: 1.5 (0.67)
- RED CHIPU low gain:1.4 (0.71)
- BLUE Chip high gain: 0.54 (1.85)
- RED CHIPL high gain: 0.52 (1.92)
- RED CHIPU high gain: 0.46 (2.17)
From KPI document:
- BLUE_1x1_225 VAL=0.461,0.483 REF=0.472
- REDL_1x1_225 VAL=0.569,0.617 REF=0.593
- REDU_1x1_225 VAL=0.543,0.567 REF=0.550
- BLUE_2x2_50 VAL=1.649,1.681 REF=1.665
- REDL_2x2_50 VAL=1.714,1.756 REF=1.735
- REDU_2x2_50 VAL=1.867,1.895 REF=1.881

ReadOut Noise, etc ) are trended

General information
Click on any of the plots to see a close-up version.
The latest date is indicated on top of the plot.
If configured,
- data points belonging to the latest date are specially marked
- statistical averages are indicated by a solid line, and thresholds by broken lines
- outliers are marked by a red asterisk. They are defined as data points outside the
threshold lines
- "aliens" (= data points outside the plot Y limits) are marked by a red arrow (↑ or ↓)
- you can download the data for each parameter set if the 'Data downloads' link shows up
