Notes. Column (1): short name of the source. The slit PA is also quoted, except when only one slit is used for the observations (see Table 1). Column (2): FWHM of the IP as derived from several sky lines. Column (3): slit width in arcsec. Column (4): seeing computed using an aperture equivalent to the slit width. Column (5): seeing computed from several stars in the acquisition image. Column (6): differential image motion monitor seeing value. It gives an approximate estimate of the real seeing during the night. Column (7): airmass during the observations.
