Notes. Ond = 2 m reflector of the Astronomical Institute AS CR Ondřejov, Rit = 1 m reflector of the Ritter Observatory of the University of Toledo, DAO = 1.22 m reflector of the Dominion Astrophysical Observatory, OHP = 1.52 m reflector of the Haute Provence Observatory, Cst = Castanet-Tolosan; Δλ = the wavelength region covered, ΔT = the time interval spanned by each dataset, where times are given in the reduced Julian dates RJD = HJD-2 400 000, Lines: Ha = Hα, He = He i 6678 Å, Si = Si II 6347 Å, and Si II 6371 Å.
