The sample contains 333 ultra-flat galaxies (UFG) at high Galactic latitudes, $|b|>10^{\\circ}$, with a blue major angular diameter of $a\\geq 1.2^{\\prime}$, blue and red apparent axial ratios of $(a/b)_b > 10$, $(a/b)_r > 8.5$ and radial velocities within 10000~km s$^{-1}$. As a control sample for them we use a population of 722 more thick RFGC galaxies with $(a/b)_b > 7$, situated in the same volume. The UFG distribution over the sky indicates them as a population of "},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1702.00266","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"}
