The following keys are used to define a CALIB FORS2 setup:
det.read.clock (= 100Kps/2ports/high_gain, 200Kps/2ports/low_gain, 625Kps/2ports/low_gain) ins.coll.name (= SR, HR) ins.opti#.name (# = 5,6,7,9,10; polarization optics, grisms e.g. G300V, and filters e.g. z_SPECIAL, GG435) seq.spec.targ (position of long slit produced by aligning MOS slitlets) ins.mask.id (identification of MXU mask e.g. +905221) det.win1.binx,det.win1.biny (= 1x1, 2x2)
