 * Below are all combinations of the OGBE BB temperature, integration capacitor and reset interval values. Note, that the parameter of the SPEC_dynamic_range_fmilt123_OBS CUS script is the ramp length, and not the reset interval! (1/16s -> 16; 1/4s -> 64; 1/2s -> 128; 2s -> 512). The integration capacitor/reset interval block is performed for two grating positions: GR-1 = 760000 and GR-2 = 490000.  * Each measurement block (OGSE BB temperature setup) runs through all combinations of integration capacitor (0.1pF, 0.3pF, 1pF, 3pF) and reset interval values (1/8s, 1/4s, 1/2s, 2s), and is performed for two grating positions (GR-1 = 760000 and GR-2 = 490000).
