Thus, we define ``quiescent'' satellites as those that have $\mgas / \mstar < 0.1$ or are classified as having spheroidal morphology if they have no cold gas constraints.
Thus, by this definition, the only star-forming, gas-rich satellites in the LG are: LMC ($\mstar = 1.5 \times 10^9 \msun$, $\mgas / \mstar \approx 0.3$) and SMC ($\mstar = 4.6 \times 10^8 \msun$, $\mgas / \mstar \sim 1$) around the MW, and LGS 3 ($\mstar = 9.6 \times 10 ^ 5 \msun$, $\mgas / \mstar \approx 0.4$) and IC 10 ($\mstar = 9 \times 10 ^ 7$, $\mgas / \mstar \approx 0.6$) around M31.
(While Sculptor has $\mgas / \mstar \approx 0.096$, we consider it quiescent based on its morphology and lack of recent star formation \citep{Weisz2014a}).

In examining the fraction of satellites that are quiescent, we group them into 1-dex bins of $\mstar$.
We do not attempt any correction for observational completeness as a function of $\mstar$, but we do take into account the maximum observed distance at each $\mstar$ when we compare with the simulations (see below).
