%Based on our above definitions of ``satellite'' and ''quiescent'' dwarf galaxies.  We group all satellite dwarf galaxies in the LG into 1-dex bins of $\mstar$ and compute the fraction that are quiescent in each bin.  We do not attempt any correction for observational completeness as a function of $\mstar$, because we measure the \emph{relative fraction} that are quiescent in each bin.  This bin, which  is likely an unbiased metric, absent metric.  %absent  significant differential completeness as a function of recent star formation, which is unlikely because star-forming galaxies are generally brighter, but the quiescent fraction is near unity across almost all $\mstar$. Figure~\ref{fig:quiescent_fraction} shows the quiescent fraction for all satellite dwarf galaxies of the MW and/or M31 versus $\mstar$ \citep[see also][]{Phillips2014, SlaterBell2014}.  We show fractions for all such satellites (blue circles) as well as separately for those in the MW (violet squares) and M31 (green triangles) halos.
