Effect of the variable initial guess radii ratio R₂/R₁ (top row) and the orbital inclination angle i (bottom row) parameters on the orbital-phase-resolved radii ratio (left column) and radial velocity (right column) curves obtained with the LSDBinary algorithm. Filled squares and triangles in the top left panel refer to the initial guess R₂/R₁ = 1.1 and 1.4, respectively. The same symbols in the bottom left panel refer to the initial guess inclination angle i values of 74° and 88°, respectively. Red stars indicate a solution corresponding to the parameter values of R₂/R₁ = 1.2 and i = 82°; a combination that represents the closest match to the true parameter values listed in Table 1.
