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 <a
