Notes. The right-hand columns separated by a vertical line show the measured equivalent widths (EWs) of emission lines. The errors are of the order of 1 Å. The sign ‘nc’ means that EW was not measured, although the line was visible because of a problem with estimating the continuum level due to low S/N. A colon designates the measurements that can be burdened with large uncertainty and are difficult to estimate. (⬧)Time at mid of exposure. ( ⋆ )Phase according to the ephemeris: HJDT0 = 2458661 + 918 × E (Table 3).
