$8.14\substack{+0.06 \\ -0.03}$ and $8.20\substack{+0.03 \\ -0.04} \ \mu\rm{Hz}$   for Star 1 and Star 2, respectively.  %The effective frequency resolution of the power spectrum for four years of \emph{Kepler} data is about $0.008 \ \mu \rm{Hz}$, and, more importantly,  \newrevise{The intrinsic observed mode line widths is about $0.5 \ \mu \rm{Hz}$. To quantify how likely it is for oscillation modes like this to overlap one another, we use the ELC model results from Section \ref{model} to calculate distributions of expected $\Delta \nu$ for each star. We find that 90\% of the time, $|\Delta \nu_1 - \Delta \nu_2| < 0.5 \ \mu \rm{Hz}$. This suggests that that, if both stars do indeed exhibit solar-like oscillations,  some amount degree  of mode overlap is likely.} %Given this, the oscillation pattern from a second star (if present) should \emph{not} appear to lie exactly on top of the oscillation pattern we do see.  Searching for a second set of oscillations is motivated by the broad, mixed-mode-like appearance of the $\ell=0$ modes in Figure \ref{fig:echelle}, where mixed modes are not physically possible, and by the faint diagonal structure mostly present on the upper left side of the $\ell=1$ mode ridge. Even though oscillation modes from the two stars should not perfectly overlap, modes of degree $\ell=0,1$ of one star can almost overlap modes of degree $\ell=1,0$ of the other star.
