The epoch is the time of primary minimum. The elements given are derived from measures of the helium lines and the small eccentricity probably should be neglected, especially since no value is given for omega. Measures of the hydrogen lines lead to the derivation of a more eccentric orbit and lower semi-amplitudes. No photoelectric light-curve is available; the system was shown to be eclipsing from photographic observations (S. Gaposchkin, Ann. Harv. Coll. Obs., 113, No. 2, 1953).
