We also include the more recent measurements or upper limits of cold atomic gas mass from \citet{Spekkens2014}.
We define ``satellite'' galaxies as those within $300\kpc$ of either the MW or M31, motivated by the observed sharp transition in star formation, gas, and morphological properties within this distance.
Observed dwarf galaxies show a tight correlation between their morphology, star formation, and cold gas content: all spheroidals have little-to-no detectable cold gas
\citep[e.g.,][]{GrcevichPutman2009, Spekkens2014} \citep[e.g.,][]{Spekkens2014} or ongoing star formation \citep[e.g.,][]{Weisz2014a}, and almost all irregulars have significant cold gas mass and ongoing star formation.
Thus, we define ``quiescent'' galaxies as those with $\mgas/\mstar<0.1$ or with colors and morphologies that resemble spheroidals if they have no cold gas constraints.
By this definition, the only star-forming, gas-rich satellites are: LMC ($\mstar=1.5\times10^9\msun$, $\mgas/\mstar\approx0.3$) and SMC ($\mstar=4.6\times10^8\msun$, $\mgas/\mstar\sim1$) around the MW, LGS 3 ($\mstar=9.6\times10^5\msun$, $\mgas/\mstar\approx0.4$) and IC 10 ($\mstar=9\times10^7$, $\mgas/\mstar\approx0.6$) around M31.
