We present the catalog of X-ray sources detected in a shallow Chandra survey of the inner 2 ^ { \circ } \times 0.8 ^ { \circ } of the Galaxy , and in two deeper observations of the Radio Arches and Sgr B2 .
The catalog contains 1352 objects that are highly-absorbed ( N _ { H } \gtrsim 4 \times 10 ^ { 22 } cm ^ { -2 } ) and are therefore likely to lie near the Galactic center ( D \approx 8 kpc ) , and 549 less-absorbed sources that lie within \lesssim 6 kc of Earth .
Based on the inferred luminosities of the X-ray sources and the expected numbers of various classes of objects , we suggest that the sources with L _ { X } \lesssim 10 ^ { 33 } erg s ^ { -1 } that comprise \approx 90 % of the catalog are cataclysmic variables , and that the \approx 100 brighter objects are accreting neutron stars and black holes , young isolated pulsars , and Wolf-Rayet and O stars in colliding-wind binaries .
We find that the spatial distribution of X-ray sources matches that of the old stellar population observed in the infrared , which supports our suggestion that most of the X-ray sources are old cataclysmic variables .
However , we find that there is an apparent excess of \approx 10 bright sources in the Radio Arches region .
That region is already known to be the site of recent star formation , so we suggest that the bright sources in this region are young high-mass X-ray binaries , pulsars , or WR/O star binaries .
We briefly discuss some astrophysical questions that this catalog can be used to address .
