Notes. Observational log and measured quantities of the Hα line. The Julian date of the middle of the exposure used for the spectra identification is plotted in the first column. The second column summarises the exposure time. The next one is the signal to noise ratio (S/N), which is determined using IRAF as the best value from several chosen intervals of the continuum. The main body of the table summarises the measured values of equivalent width (W), radial velocity (RV) and line intensity (F/Fc) for both red and violet peaks. The last two columns are radial velocities of the central depression and the centre of the line measured by the mirroring of the wings. When the “bump” in the violet peak appeared, the values for both “bumps” are written. The value for the blue “bump” of the violet peak is written at the first line of the corresponding date. The result for the red “bump” is written at the following line. The values in brackets were not used for the analysis due to the high uncertainty. The equivalent width values are obtained by the numerical integration and their errors are calculated following Vollmann & Eversberg (2006). Necessary S/N values for the error estimate are computed from the fix interval of the continuum in the line neighbourhood. Radial velocities of the peaks, the central depression, and line intensities are measured using the line-profile fitting (MAXIPES, Mikulášek et al. 2006). The errors tabulated here are the formal errors of the fitting which are probably underestimated.
