{\it Top panel}: summary of the properties of CXO J1745-28 and  X-ray bright ($>$$10^{35}$~erg~s$^{-1}$)  binary systems.   
{\it Middle panel}: remaining spectroscopically or photometrically confirmed binaries. {\it Bottom panel}: binary candidates selected
on the basis of their X-ray  properties (see Sect.~4). Stars are ordered in terms of decreasing X-ray flux, with errors given
 for this parameter and  orbital period if provided in the original study. We quote dynamical masses only, with
those given in italics representing lower limits. Regarding individual sources,
WR20a, 22 and 25~have all been flagged as X-ray variable 
(Naze et~al. \cite{naze}; Gosset et~al. \cite{gosset};  Pollock \& Corcoran \cite{pollock06}), 
while the X-ray fluxes given for the Arches sources assume a 1T fit; a similar fit for CXO J1745-28 
 results in  a directly comparable flux (Wang et~al. \cite{wang}; Mikles et~al. \cite{m06}). The converse is also true;  the   
2T (0.9~+~5.8~keV) fit for F9 favoured by Yusef-Zadeh et~al. (\cite{yz02}) yields $L_{\rm x} \sim 8 \times 10^{34}$~erg~s$^{-1}$; 
we choose to present the 1T fits for all three stars  since Yusef-Zadeh et~al. (\cite{yz02}) only present a spectral fit for F9. References for the values quoted in the table are:
