Example of fine-tuning the inclination angle parameter i by minimising deviations of the R₂/R₁ (bottom) and RV (top) measurements obtained with the LSDBinary algorithm from their respective constant value and pure orbital motion-driven curve. The open circles, red stars, and open squares show the results obtained for the orbital inclination angle i = 76°, 82°, and 88°, respectively. The solid black lines shows the orbital motion-driven RV curve of the primary and the constant systemic value of R₂/R₁ = 1.19 in the top and bottom panels, respectively.
