We used the Plateau de Bure Interferometer to synthesize \\CFP\\ J=1-0 absorption at 102.6 GHz toward the core of the distant HII region W49N at l = 43.2\\degr, b=0.0\\degr, and we modeled the fluorine chemistry in diffuse/translucent molecular gas. We detected \\CFP\\ absorption over a broad range of velocity showing that \\CFP\\ is widespread in the \\HH-bearing Galactic disk gas. Originally detected in dense gas in the Orion Bar and Horsehead PDR, \\CFP\\ was subsequently detected in abs"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1505.07927","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"}
