To draw points from the Fermi-Dirac-like distribution in Eq.~\ref{eq:fermidirac} we would draw values uniformly between 0 and 1 and then for each value invert the cdf.  Unfortunately the cdf function cannot simply be inverted. However, the cdf can easily be computed over a fine grid of values and the corresponding $h_0$ value can be calculated via interpolation. It is definitely worth testing out this as a prior for the searches. I should also look into the Jacobian between this and a prior distribution as I might need that when thinking about using posterior samples of $h_0$ to work out the underlying distributions of $h_0$ (or $\varepsilon$/$Q_{22}$).
