Observations covering a time interval of about 37000-days (101.3-years) can be reconciled with a constant orbital period of (14.0691+/-0.00004)-days. The high orbital eccentricity of 0.555+/-0.009 was also confirmed.

New spectral observations confirm that there is a periodic variation of the systemic velocity. Together with new evidence from astrometric observations (also analyzed here), they confirm the existence of a third body in the system with an orbital period of about 9600-days (26.3-years), rather than 4156-days, as reported earlier. Application of the disentangling technique to the H alpha spectra with good S/N ratios did not allow detection of spectral lines of either the secondary or tertiary components.
