This is the instrument performance plot for FORS2 DETMON GAIN. The gain values (e-/ADU) are calculated by the detmon_opt_lg recipe (using the Photon Transfer Curve - PTC, method). The data come from a dedicated detmon calibrations consisting of sets of paired flat fields and bias frames with identical exposure time.

The reference values are adopted from the FORS2 User Manual.
