Chandra X-ray sources toward Galactic Center
Listed in IVOA Registry (Virtual Observatory)
We present a catalog of 2357 point sources detected during 590ks of Chandra observations of the 17x17' field around Sgr A*.
Description
This field encompasses a physical area of 40x40pc at a distance of 8kpc. The completeness limit of the sample at the Galactic center is 10^31^erg/s (2.0-8.0keV), while the detection limit is an order of magnitude lower.
The 281 sources detected below 1.5keV are mainly in the foreground of the Galactic center, while comparisons to the Chandra deep fields at high Galactic latitudes suggest that only about 100 of the observed sources are background AGNs.
