At an assumed distance of 7.1 kpc, the data gave a persistent unabsorbed luminosity of $3.4\\times10^{36}$ erg cm$^{-2}$ s$^{-1}$ in 0.6 $-$ 55 keV. The source was in a relatively bright low/hard state, wherein the 0.6 $-$ 55 keV spectrum can be successfully explained by a \"double-seed\" Comptonization model, incorporating a common corona with an electron temperature of $\\sim13$ keV. The seed photons are thought t"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1603.05913","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"}
