This plot

The master bias is averaged along its columns. Then the rms of the resulting 1-dimensional frame is used to check for the presence of a bias pattern (predominantly in low gain, 2x2 readout) Details can be found in the plot tutorial.

DB Name: fors2_bias
TPL.ID: img_cal_bias
Fits header keyword: NA, calculated by the QC script
QC1 DB parameter: pattern

 
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
