The above histogram transformed into the real angle ψ in solid line and smoothed to bins of 1°. Red dotted curves show key individual objects in order to illustrate some of the features of the overall distribution. The blue dashed histogram is the reproduction of the theoretical histogram published by Fabrycky & Tremaine (2007) and solely plotted over. a) HD 189733b; b) XO-3b; c) HD 80606b; d) WASP-8b; e) WASP-15b; f) Hat-P-7b. The black dotted line shows ψ = 30°. Above that, planets are considered misaligned.
