Notes.
Image Quality from the Shack-Hartmann sensor of the VLT active optics at 650 nm at the airmass of observations.
Resolving power measured from emission lines in ThAr calibration frames. The listed values correspond to the Blue and Red arm spectra, respectively, for ESPRESSO, and to the Blue, Lower-Red, and Upper-Red spectra for UVES. For the latter instrument, the effect of an IQ smaller than the slit width in some cases is taken into account.
