Notes. Columns 1 and 2 give the civilian date and UT time of the midpoint of the observation; Col. 3 gives the number of the slitlet where the star was located. Because of the Wollaston mask, only evenly numbered slitlets are available for observations in spectropolarimetric mode; slitlets are numbered in increasing order from the top of the CCD to the bottom as described in the FORS user manual; the spectra of the star in slitlets from Nos. 2 to 10 are located on chip “Norma” and the spectra of the stars in slitlets from Nos. 12 to 18 on chip “Marlene”. Part of the field of view of slitlet No. 12 falls in the gap between the two chips and in most of the cases could not be used. The main target was always placed in slitlet 10. Columns 4 and 5 give the J2000 RA and Dec and the target name as identified through SIMBAD or other catalogues; Col. 7 gives the V magnitude, except entries flagged with a ∗ for which the magnitude refers to the J filter; Col. 8 is the star’s spectral type; Cols. 9 and 10 give the total exposure time and the S/N per Å; Cols. 11 and 12 give our field determination from the reduced Stokes V profiles, ⟨ B_z ⟩, and from the null profiles, ⟨ N_z ⟩. All spectra were obtained with grism 1200B and a 1′′ slit width, except those of the magnetic standard stars that were obtained with a 0.5′′ slit width.
