I\/ll review the angular correlation function results <br />
from previous X-ray and optical surveys <br />
and present the angular correlation function of the X-ray point sources <br />
in the Spitzer Wide-area InfraRed Extragalactic survey (SWIRE) field <br />
observed with the Chandra X-ray observatory. <br />
The Chandra/SWIRE survey is a moderate-depth (70 ksec) observation, <br />
contiguously covering 0.6 square degrees <br />
in the Lockman Hole field of the Spitzer/SWIRE Legacy Survey. <br />
I will discuss the angular correlations of the X-ray point sources <br />
in the broad (0.5-8 keV), soft (0.5-2 keV), and hard (2-8 keV) band, <br />
and the flux dependent clustering of the X-ray point source.
