By fitting the appropriate isochrones to the observed sequences of the clusters in five different color--magnitude diagrams, the weighted averages of distance moduli and heliocentric distances ($(V_0$--$M_{V}), d$(kpc)) are $(11\\fm90\\pm 0\\fm06, 2.4\\pm 0.06$) for Be~89, $(9\\fm58\\pm 0\\fm07, 0.81\\pm 0.03$) for Ru~135, and $(11\\fm16\\pm 0\\fm06, 1.7 \\pm 0.05$) for Be~10, and the weighted averages of the ages $(\\l"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1008.2867","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"}
