Comparison of observations and the phoebe2 model of δ Ori with χ² = 604. The values of the effective temperature of the primary T₁ and the third light l₃ were fixed. The upper panel shows the phased LCs in the blue and red BRITE filters. The lower panel shows the RV curves for the primary Aa1 (forestgreen greenblack) and the secondary Aa2 (pypurple purpleblack). The grey points correspond to our model, the red lines to the residuals, or contributions to χ².
