(\cite{n09}), the YHGs from this work (Sect.~6) and the RSGs from Mengel \& \mbox{Tacconi-Garman} (\cite{mengel}). Where appropriate, the Notes column lists stars as {\bf E}clipsing or {\bf A}periodic photometric variables (Bonanos \cite{bonanos}), {\bf X}-ray (Clark et~al. \cite{c08}) and {\bf P}oint and/or {\bf R}esolved radio (Dougherty et~al. \cite{d09}) sources. Finally, the binary status of 5~stars -- as determined by Ritchie et~al. (\cite{benbin}) from multiepoch radial velocity spectroscopic data -- is presented, noting that insufficent data currently exist to confirm the status of the other stars (but note Sect.~6 for W265).} \end{table}
