Notes. The velocity $\gamma_1$ is based on Ondrejov data, $\gamma_2$ on Rozhen data, $\gamma_3$ on OPD data (Vieiria et al. 2004), and $\gamma_4$ on historical data of Plaskett & Young (1919). In solution IV $\gamma_5$ , $\gamma_6$ , $\gamma_7$ , and $\gamma_8$ stand for $\ensuremath {{\rm H}\alpha }$ , He I 6678 Å, Si II 6347 Å, and Si II 6371 Å, respectively.
