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.

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
