We estimate the two point correlation function in redshift space, $\\xi(s)$, for several subsamples of ORS, spanning nearly a factor of 30 in volume and detect significant variations in $\\xi(s)$ among the subsamples covering small volumes. For volumes \\gtsima $(75 h^{-1} {\\rm Mpc})^{3}$ the ORS subsamples present very similar clustering patterns. Powerlaw fits to $\\xi(s)$ give best-fit values in the range $1.5 \\leq \\gamma_{s} \\leq 1.7 $ and $6.5 \\leq s_{0} \\leq 8.8 h^{-1}$ Mpc for several sam"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/9608001","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"}
