Notes. RA and Dec refer to the coordinates of the quasar. The slit position angle (PA) was selected to match the candidate host galaxy from imaging data (Rao et al. 2011), and is defined so that N = 0, E = 90°. All observations were taken with a slit-width of 1.31 arcsec. The tabulated airmass corresponds to the mean value calculated from the nominal header-values at start and end for each exposure. The seeing, as the FWHM of a summed profile in ten pixels along the dispersion direction, was measured in the combined spectrum of the quasar. As the seeing-measurements varied temporally and in wavelength non-trivially, we report the observed ranges. We define the systematic offset in the wavelength-solution as Δλsyst. = λcalib. − λUVES.
