\paragraph{SFR, IMF and z}
\label{par:sfr_imf_and_z}
The authors assume a constant Star Formation Rate (0-12Gyr) and a time independent IMF \cite{kroupa_variation_2001} . The metallicity parameter [Fe/H] is constant for the duration of a BSE code run (i.e. it is age-independent and uniform) so the authors combined several runs with different upper and lower IMF limits in order to mimic the observed [Fe/H] distributions.

\paragraph{Binary parameters $f(a, q, e)$}
\label{par:_f_a_q_e_}
For the binary runs the authors make simplifying first assumption that the function $f(a,q,e)$ is separable and assign 3 independent functions to $f(a)$, $f(q)$ and $f(e)$ respectively.

\section{Population Synthesis}
\paragraph{}
It is straightforward to show the probability of an eclipse at any depth is $P_eo = r_s + r_g$ but the authors wish to study the probability of an eclipse of \textbf{any specified} magnitude depth.
In order to calculate this probability, the function $i(\Delta m)$ must be derived. Although the maximum primary eclipse depth $\Delta m$ is a well defined function of the inclination angle i, iteration is needed to find this inverse function $i(\Delta m)$
With a random distribution of inclinations the probability of a primary eclipse deeper than $\Delta m$ is $cos(i(\Delta m))$
