Notes. The seeing values are measured by the DIMM seeing monitor in the V band and the FWHM value corresponds to the one measured in the extracted PSF, used to fit the positions of the stars. In the case of the NGC 6388 data, the first five frames are taking using only ground-layer correction and frames 6–30 are in full MCAO mode. In the case of the 47 Tuc data, all frames were taken using ground-layer correction.
