This plot

The gain is derived from a set of paired flat fields with identical exposure time, using the Photon Transfer Curve (PTC) method. Since 2013-08-01, flats covering the full dynamic range are taken into account, also flats already in the non-linear regime, for which the PTC is not corrected for. A smaller slope in the PTC results in higher gain values. For more information see the plot tutorial page.  


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
