Comparison of the viewing angle KDEs described in Appendix D associated with the four-epoch fit (where uninformative priors on jet geometry are desired): the implied fiducial prior actually used in this study (p, blue; uniform in θ_v), the resulting fiducial posterior (green), the desired target prior (q, orange; uniform in ﹩\cos (\,{\theta }_{\rm{v}}\,)﹩, subject to the constraint θ_cp  <  θ_v), and the “new” corrected posterior that results from scaling the fiducial posterior by ﹩\tfrac{q}{p}﹩.
