Trending plots for the bias read-out noise.
QC parameters are derived from each of 32 detectors of OmegaCAM BIAS frames.
DB Name: omegacam_readnoise
Fits header: QC.READNOISE
QC1 DB: qc_ron / qc_temp_mosaic_plate
Description:
The bias read-out noise as measured from the pipeline product frame READNOISE_ADU
Setup:
BIN.X / BIN.Y / READ.MODE / READ.SPEED = 1/1/normal/normal
These Health Check plots describe:
Fig. 1 readnoise_AVG: The bias read-out noise averaged over
all 32 detectors (in ADU).
This plot is sensitive to any changes common to all detectors.
Fig. 2 readnoise_ALL: The bias read-out noise for each
individual detector (in ADU). This plot is sensitive changes in individual
detectors.
Fig. 3 readnoise_RMS: The rms of the bias read-out noise averaged over
all 32 detectors (in ADU).
Fig. 4 score_outliers: Scores of the bias readnoise as
measured for each of the 32 detectors.
Green = within the defined thresholds.
Red = beyond the defined thresholds.

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
