This plot

Read Out Noise values for all DITs are shown for three readout modes: Double ReadResetRead ("DCR"), Multiple FowlerNsampling ("FNS") and Uncorrelated ("UCR"). The data calculated from darks taken with different integration time values (DIT) are displayed together.  

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
