Effect of incorrectly assumed binary parameters on the RV curve of the primary component. Top row: effect of incorrectly assumed initial guess T_eff of the primary component, with R₂/R₁ being fixed to its true value of 1.19 (see Table 1). Left and right panel shows the effect of underestimated and overestimated effective temperature values, i.e. T_eff = 8500 K and 9100 K, respectively. Red stars show the optimal solution obtained with LSDBinary corresponding to the orbital inclination angle i = 82°. Two more solutions corresponding to i = 74° (open circles) and 90° (open squares) are shown for comparison. Bottom row: combined effect of incorrectly assumed initial guess T_eff of the primary and components’ radii ratio R₂/R₁. Left and right panel shows the cases of underestimated and overestimated parameters: T_eff = 8500 K and R₂/R₁ = 1.02, and T_eff = 9100 K and R₂/R₁ = 1.36, respectively. See text for details.
