Our 9 ACIS-I fields cover an effective solid angle of 0.4 deg$^{2}$ and reach a depth of $3 \\times 10^{-16}$ \\ergpcmsqps in the 0.4--2 keV band and $3 \\times 10^{-15}$ \\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 i"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0302137","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
