Notes. The coordinates, brightness and spectral type were taken from the SIMBAD Astronomical Database. Type indicates if the star is a polarized standard star (PolStd), unpolarized standard star (unPolStd), or one of our science targets (SCI). No. of Epochs is the number of epochs observed with a particular instrument: FORS2 (VLT), CAFOS (CAHA), or AFOSC (Asiago).
