This plot

Averages across all detectors for bias QC1 parameters.

The first row shows the average of Q1 to Q4 for the median bias level and the ron of the master frame (noise_master). The average is mainly sensitive to changes that affect all quadrants. The second row shows the rms across Q1 to Q4 for the QC parameters. This is mainly sensitive to changes that affect only one quadrant.  


General information

Click on any of the plots to see a close-up version. The latest date is indicated on top of the plot, data points belonging to that date are specially marked.

If configured,

  • 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
