Trending plots for the detector linearity.
QC parameters are derived from each of 32 detectors of OmegaCAM dome flat frames.
DB Name: omegacam_detlin
Fits header: QC.LIN.EFF
QC1 DB: qc_lin_eff / qc_num_bpm
Description:
The detector linearity as measured from the detector monitoring
pipeline product DET_LIN_INFO and BP_MAP_NL
Setup:
BIN.X / BIN.Y / READ.MODE / READ.SPEED = 1/1/normal/normal
These Health Check plots describe:
Fig. 1 non-linearity_AVG: The effective non-linearity
correction averaged over all 32 detectors.
This plot is sensitive to any changes common to all detectors.
Fig. 2 non-linearity_ALL: The effective non-linearity
correction for each individual detector. This plot is sensitive changes in individual
detectors.
Fig. 3 flux_level_AVG: The flux level at which the
effective non-linearity correction is applied averaged over all 32
detectors (ADU).
Fig. 4 score_outliers: Scores of the effective
non-linearity correction 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
