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

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
