This plot

Trending plot for GAIN (conversion factor from ADU to electrons, e-/ADU).

The gain is determined from imaging lamp flats taken with the R filter and with the 225kHz,1port,Low read-out mode. Please note that in the VIMOS headers this quantity is written as CONAD.

Template ID: img_cal_ScreenFlat. Pipeline recipe: vmimflatscreen.  


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
