Grazing eclipses haven't been confirmed from MOST photometry analysis in 2016MNRAS.458.1964T. Eccentric system. Apsidal period has been published as 117.9 yrs (2016A&A...590A..54H) or 139 yrs (2016MNRAS.458.1964T). BCEP pulsations arise from the primary component and have an amplitude <0.01 mag. The previously reported period (0.1738 d.) is present but with a much smaller amplitude in MOST data, which shows several periods, the larger amplitude one being 1.441 d. (2016MNRAS.458.1964T).
Eclipse amplitude is less than 0.01 mag. Ellipsoidal variability, 0.03 mag.

The Table gives the epoch of Min for the ellipsoidal variability and Porb. The depth of Min II up to 0.08m. SB 2. e = 0.205 +- 0.004. Apsidal motion: Pi = 108a +- 5a. Pulsations: P var, P = 0.17378587d (1908 - 1956); since 1956 Max = 2445405.63 + 0.17378680d*E [E.Chapellier, J.C.Valtier, J.P. Sareyan, J.M.Le Contel, D.Ducatel, P.J.Morel, AsAp 143, N2, 466, 1985.]. A var. 3 companions according to lunar occultation observations: 3.1m, 0.0025"; 4.5m, 0.05"; 7.5m, 0.5". Soft X-ray source, LX/Lbol = 2.9*10**(-8).
