X-ray survey of the Galactic Bulge (CXOGBS)
Listed in IVOA Registry (Virtual Observatory)
We provide the Chandra source list for the last ~quarter of the area covered by the Galactic Bulge Survey (GBS).
Description
The GBS targets two strips of 6x1{deg} (12sq.deg. in total), one above (1<{deg}b<2{deg}) and one below (-2{deg}<b<-1{deg}) the Galactic plane in the direction of the Galactic Center at X-ray, optical and near-infrared wavelengths. For the X-ray part of the survey we use 2ks per Chandra pointing.
We find 424 X-ray sources in the 63 Chandra observations we report on here. These sources are in addition to the 1216 X-ray sources discovered in the first part of the GBS survey described before. We discuss the characteristics and the X-ray variability of the brightest of the sources as well as the radio properties from existing radio surveys.

We point out an interesting asymmetry in the number of X-ray sources as a function of their Galactic l and b coordinates which is probably caused by differences in average extinction towards the different parts of the GBS survey area.
