Notes. The columns contain from left to right: (1) source name; (2) right ascension (J2000); (3) declination (J2000); (4) start time of the observations; (5) exposure time; (6) average airmass; (7) average seeing at Zenith in the R band, and (8, 9, 10) S/N ranges measured in selected regions of the continuum in the UVB, VIS, and NIR arms, where no obvious features were present. The slit widths are the same for all observations: 1.3′′, 1.2′′ and 1.2′′ for the UVB, VIS, and NIR arm, respectively.
