This plot
Trending plots for the bias read-out noise for four specific detectors.
QC parameters are derived for detectors ESO_CCD_#82, #81, #83, and #75 from
the OmegaCAM BIAS_READNOISE frames.
DB Name: omegacam_readnoise
Fits header: QC.READNOISE
QC1 DB: qc_ron
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 read_noise: The bias read-out noise for the
least-stable detector (#82: red points) and for more stable detectors
#81 (green points), #83 (blue points), and #75 (black points) (in ADU).

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
