Notes. ΔPA refers to the amplitude of the parallactic rotation, DIT (Detector Integration Time) to the single exposure time, NDIT (Number of Detector InTegrations) to the frame number in a single datacube, Nexp to the number of datacubes of the observing sequence, ϵ to the seeing, τ0 to the mean correlation time of the atmospheric turbulence, and CE to the coherent energy during the observations. The seeing is measured by the DIMM at 0.5 μm, hence includes high-frequency terms unseen by the AO wavefront sensor. The last two quantities are estimated by the AO system at 0.55 μm and 2.17 μm, respectively. The next three columns indicate the image binning used for constructing the science mastercube (Sect. 3.3.1), the number of frames in the mastercube, and the corresponding total exposure time on the target. For the observing mode, ASDI-4 refers to FQPM+SDI+ADI and ASDI to SDI+ADI.
