Notes.
(a) Priors are assumedto be flat in the given range for the parametrization given in this table, and zero outside, except
χ0, for which a 180°
periodicity is applied when the Metropolis algorithm draws values outside the given range.
(b) Corresponding to a cube depth in the interval 
.
(c) Corresponding to a density in the interval
