This plot

For the master an expected master bias noise is calculated from the ron of the raw data, divided by the square root of the number of frames that were used to create the master bias. Then the population standard deviation of the pixel values of the master bias is determined, excluding all pixels that differ more than three times the expected ron from the median level of the master bias. Details can be found in the plot tutorial.

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
