This plot

The difference between the first and the second input raw biases (in ADU) is computed. The population standard deviation of the pixel values of this difference, divided by the square root of 2, is taken as the RON. Details can be found in the plot tutorial.

DB Name: fors2_bias
TPL.ID: img_cal_bias
Fits header keyword: QC.RON
QC1 DB parameter: RON_r

 
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
