\subsection{Observed Quiescent Fractions for Satellites}
Based %Based on our above definitions of ``satellite'' and ''quiescent'' dwarf
galaxies, we galaxies.
We group all
satellites 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 is likely an unbiased 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 $\mstar$.
