Notes. Three different values for slit widths and exposure times correspond to the UVB, VIS, and NIR arms, respectively. The exposure time for NIR data is subdivided into 3 integrations (NDIT). “Seeing” refers to the “delivered seeing corrected by airmass” in the VIS Band and the value of “Airmass” is recorded at the start of exposure. The last column gives the position angle at the start of the observations.
