Notes. Column 3 indicates the phase using the ephemeris of Table 2 of Nazé et al. (2015) (for BI 57 they refer to a period of 787 d). Columns 4 to 6 show the total EWs obtained when integrating the full line profiles (i.e. absorption+emission; this was performed over the intervals 4680–4700 Å for HeII 4686, 4840–4890 Å for Hβ, and 6558–6574 Å for Hα). Columns 7 to 9 give the EWs integrated over the emission component only considering as continuum the bottom of the line, as done by Walborn et al. (2015).
