Notes. We list the observing date, time (UT), duration of the observation, and airmass thereof (Cols. 2–5). The calibrators used for the atmospheric correction are also given, with the calibrator star, time, and airmass of the measurements (Cols. 6–8) and the range of orientation angles of the slit for all observations (clockwise with respect to east. The mean orientation for each object (
) is listed at the top of each panel in Fig. 2) (Col. 9).
