Notes. Main parameters of the observations: date/time, order of execution in the sequence, filter, name of the object, type of object (target or reference, or background image), identifier of the sequence, number of groups, number of integrations, number of dither positions (9 is for the SGD, 4 or 1 is a classical dither, 2 is for the background), total exposure time per dither.
