Estimates of ψ as a function of λ under the isotropic stellar inclination assumption, for three different values of the orbital inclination. Distributions for ψ are computed as described in the main text, assuming Gaussian distributions for λ and i_p with respective standard deviations of 5° and 1°. Plotted values are the medians of the ψ distributions, with error bars set to their 68% HDIs.
