摘要
We present the first results from a wide solid angle, moderately deep {\it Chandra} survey of the Lockman Hole North-West region. Our 9 ACIS-I fields cover an effective solid angle of 0.4 deg and reach a depth of \ergpcmsqps in the 0.4--2 keV band and \ergpcmsqps in the 2--8 keV band. The best fit logN-logS for the entire field, the largest contiguous {\it Chandra} field yet observed, matches well onto that of the {\it Chandra} Deep Field North. We show that the full range of the `cosmic variance' previously seen in different {\it Chandra} fields is reproduced in this small region of the sky. Counts-in-cells analysis shows that the hard band sources are more strongly correlated than the soft band sources.
