This parameter is determined from an overscan-subtracted calibration
lamp exposure in LSS mode (taken with the template
FORS2_lss_tec_waveLampcheck). The total signal is integrated and
normalized by the exposure time and the total number of original CCD
pixels (keeping into account possible binning). More information can
be found in the plot
tutorial.

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
