Notes.Porb: orbital period. Tp: time passage through periastron. e: eccentricity. K: radial velocity semi-amplitude of the primary. vγ: systemic velocity. ω: argument of periastron. Ω: position angle of the ascending node. a: semi-major axis. i: orbital inclination. mH: apparent magnitude in H. Ppuls: pulsation period. T0: reference epoch of maximum light. Ai,Bi: Fourier parameters.
