CLASXS: X-ray catalog
Listed in IVOA Registry (Virtual Observatory)
We present the X-ray catalog and basic results from our Chandra Large Area Synoptic X-ray Survey (CLASXS) of the Lockman Hole-Northwest (LHNW) field.
Description
Our nine ACIS-I fields cover a contiguous solid angle of 0.4{deg}^2^ and reach fluxes of 5x10^-16^ergs/cm^2^/s (0.4-2keV) and 3x10^-15^ergs/cm^2^/s (2-8keV). Our survey bridges the gap between ultradeep pencil-beam surveys, such as the Chandra Deep Fields (CDFs), and shallower, large-area surveys, allowing a better probe of the X-ray sources that contribute most of the 2-10keV cosmic X-ray background (CXB).
We find a total of 525 X-ray point sources and four extended sources.
