Distribution of the true angle ψ using the distribution for i_⋆ from the peak-bagging, and with the assumption of normal distributions for the planetary inclination i_p and projected angle λ. For i_p the value from Van Eylen et al. (2013) was adopted, while λ was taken from Albrecht et al. (2012). The dark- and light-grey regions of the distribution correspond to the 68% and 95% credible regions. The dashed curve gives the distribution assuming instead an isotropic distribution for i_⋆, i.e., flat in cos i_⋆. We indicate also which values of ψ correspond to a retrograde or prograde orbit of HAT-P-7b.
