Trending plots for the detector dark current and particle rate.
QC parameters are derived from each of 32 detectors of OmegaCAM dark frames.
DB Name: omegacam_dark
Fits header: QC.DARK.CURRENT / QC.PARTICLE.RATE
QC1 DB: qc_dark_current / qc_particle_rate
Description:
The dark current and particle rate is measured from the pipeline product MEAN_DARK
Setup:
BIN.X / BIN.Y / READ.MODE / READ.SPEED = 1/1/normal/normal
These Health Check plots describe:
Fig. 1 dark_current_AVG: The dark current averaged over
all 32 detectors (in ADU/pixel/hour).
This plot is sensitive to any changes common to all detectors.
Fig. 2 gain_ALL: The dark current measured for each
individual detector (in ADU/pixel/hour). This plot is sensitive changes in individual
detectors.
Fig. 3 particle_rate_AVG: The dark frame particle rate
averaged over all 32 detectors (in particles/cm^2/hour).
Fig. 4 score_outliers: Scores of the dark current 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
