Title of program: MAGBIN Catalogue Id: AACG_v1_0 Nature of problem Given a spectroscopic ephemeris of a double star system suffering tidal distortion, this program finds the inclination of the orbital plane, i, and the r_1/a ratio (r_1 = primary star radius, a = semi major axis of the orbit) from the variation of brightness with time (the 'light curve'). It also finds the period, P, amplitude and phase of the oscillation if one of the stars is variable. It also finds the mean brightness of the star and instrumental changes in this value if the star is observed ov ...
