Example of a 1D peak. This peak in p(x) has peak volume (yellow area) p_v(a) = 1.5 × 10^-72, while the peak height is p_h(a) = 2.9 × 10^-73, which is the maximum probability attained at βa = 1209. The peak location L(a) is the extent from x_start = 1204 to x_end = 1216, which corresponds to the local minimum attained at a = 1212. The depth is D(a) = 0.711.
