Trending plots for the detector gain.
QC parameters are derived from each of 32 detectors of OmegaCAM dome flat frames.
DB Name: omegacam_detlin
Fits header: QC.GAIN / QC.GAIN.ERR
QC1 DB: qc_gain / qc_gain_err
Description:
The detector gain as measured from the detector monitoring pipeline product GAIN_INFO
Setup:
BIN.X / BIN.Y / READ.MODE / READ.SPEED = 1/1/normal/normal
These Health Check plots describe:
Fig. 1 gain_CCD_69: The gain averaged over
all 32 detectors used to be monitored (in e-/ADU). Since 2024-05-28, the gain of
the DET_ID=ESO_CCD_69 is followed.
This plot is sensitive to any changes to the detector ESO_CCD_69.
Fig. 2 gain_ALL: The gain measured for each
individual detector (in e-/ADU). This plot is sensitive to changes in individual
detectors.
Fig. 3 gain_err_AVG: The error in the gain averaged over
all 32 detectors (in e-/ADU) used to be monitored. Since 2024-05-28,
the error in gain of the DET_ID=ESO_CCD_69 is followed.
Fig. 4 score_outliers: Scores of the gain level as
measured for each of the 32 detectors.
Green = within the defined thresholds.
Red = beyond the defined thresholds.

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
