This plot
Trending plots for the median bias levels.
QC parameters are derived from each of 32 detectors of OmegaCAM BIAS frames.
DB Name: omegacam_bias
Fits header: QC.MASTER.BIAS.MEDIAN / QC.MASTER.BIAS.STDEV
QC1 DB: qc_bias_median / qc_bias_std / qc_temp_mosaic_plate
Description:
Median and standard deviation of the MASTER_BIAS pipeline product frame
Setup:
BIN.X / BIN.Y / READ.MODE / READ.SPEED = 1/1/normal/normal
These Health Check plots describe:
Fig. 1 level_AVG: The median bias level averaged over
all 32 detectors (in ADU).
This plot is sensitive to any changes common to all detectors.
Fig. 2 level_ALL: The median bias level for each
individual detector (in ADU). This plot is sensitive changes in individual
detectors.
Fig. 3 rms_AVG: The standard deviation of the
bias level measured for EACH detector, and then averaged over all detectors (in ADU).
Fig. 4 score_outliers: Scores of the bias 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
