$^{a}$ For the double-peaked H$\alpha$ line radial velocities are given for the bluewards and redwards peaks, $V_{\rm r}$(b) and  $V_{\rm r}$(r), the central absorption feature, $V_{\rm r}$, 
and the separation of the two peaks, $\Delta V_{\rm r}$. \\
$^{b}$ Except where noted, errors are conservatively estimated at $\pm$4~km~s$^{-1}$ for the H$\alpha$~radial velocities and ${\le}\pm8$~km~s$^{-1}$ for the He~I~$\lambda$7065 
and Pa$\delta$~radial velocities. \\
$^{c}$ The equivalent width of the Pa$\delta$ line includes the absorption components seen in Fig.~\ref{fig:HaPd} on either side of the emission line. If these are excluded, then the equivalent width is broadly constant at $\sim$1.35~$\pm$ 0.15~${\rm \AA}$ (with increased errors due to the difficulty of estimating the continuum).
