Table 3: Summary of the X-ray and optical properties of the X-ray point sources with high mass stellar counterparts. Columns 1-3 summarise the X-ray nomenclature, photon counts and Hardness Ratio, noting that only 164706.2-455048 was found to be variable in these observations; we highlight this by presenting the photon count in italics. Column 4 is the number of the source on the finding chart (Fig. 6); we strongly advise that these numbers should not form the basis for a new naming convention. Column 5 contains the optical designation (sources with 2MASS or Piatti et al. (1998) designations are indicated), with Cols. 6-9 presenting relevant broadband BVRI photometry. The current spectral classifications for the counterparts are given in Col. 10, noting that for those sources for which no entry is given but for which photometric data are available, we predict a spectral classification earlier than B0.5Ia (Sect. A.3). Finally, in Col. 11 we flag those stars which Bonanos (2007) find to be Eclipsing, Periodic or Aperiodic photometric variables.
