Trending plots for the number of bad (hot + cold) pixels: ALL filters (except u_g_r_i_SDSS).
QC parameters are derived from each of 32 detectors of OmegaCAM TWILIGHT master flat frames.
All master dome flat filters can be compared in a single Health Check
plot since their flux levels are normalized.
DB Name: omegacam_twilight
Fits header: QC.NUMBER.BAD.PIXELS
QC1 DB: qc_bad_pixels
Description:
The number of bad (hot + cold) pixels combined in the master twilight flat pipeline product frame BAD_PIXELS_MAP
Setup:
BIN.X / BIN.Y / READ.MODE / READ.SPEED = 1/1/normal/normal
These Health Check plots describe:
Fig. 1 number_badpix_AVG: The number of bad (hot + cold) pixels averaged over all 32 detectors.
This plot is sensitive to any changes common to all detectors.
Fig. 2 number_badpix_ALL: The number of bad (hot + cold) pixels for each individual detector. This plot is sensitive changes in individual detectors.
Fig. 3 score_outliers: Scores of the number of bad (hot
+ cold) pixels as detected in 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
