This plot

Dark frames are taken rarely with 2x2 bin, low and high gain. Those with low gain usually have neglible dark current in ADU. The typical exposure time is 1800 sec. The FORS pipeline generates master DARKs from input raw DARKs with master BIAS subtracted. Dark current: is computed from the median master dark frame level in ADU/hr/px and transformed into electrons by using the conversion factor CONAD. More information can be found on the plot tutorial page

DB Name: fors2_dark

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
