Notes. (a): DIT corresponds to the Detector Integration Time per frame, NDIT the number of DITs per exposure and NEXP the number of exposures in the template. (b): ∆PA is the amplitude of the parallactic rotation. (c): values extracted from the updated Differential Image Motion Monitor (DIMMa) info, averaged over the sequence.(d): τ0 correspond to the atmosphere coherence time.
