This plot

Trending plots for the number of hot pixels in the bias frames.

QC parameters are derived from each of 32 detectors of OmegaCAM BIAS frames.

DB Name: omegacam_bias
Fits header: QC.NUMBER.HOT.PIXELS
QC1 DB: qc_bias_hotpixels / qc_temp_mosaic_plate

Description:
The number of hot pixels detected in the bias pipeline product frame HOT_PIXELS_MAP

Setup:
BIN.X / BIN.Y / READ.MODE / READ.SPEED = 1/1/normal/normal

These Health Check plots describe:
Fig. 1 hot_pixels_AVG: The number of detected hot pixels averaged over all 32 detectors. This plot is sensitive to any changes common to all detectors.
Fig. 2 hot_pixels_ALL: The number of hot pixels found in each individual detector (detectors: ESO_CCD_68, ESO_CCD_82, ESO_CCD_84, and ESO_CCD_90 consistently show very high values). This plot is sensitive to changes in each detector.
Fig. 3 score_outliers: Scores of the number of hot pixels 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
