The inner profile is well fit by a nonisothermal core model with a core radius of 0.41\" +/- 0.02\" (34 pc). At an assumed distance of 16.9 Mpc, the deprojected luminosity density reaches $\\sim 2.0 \\times 10^3 L_{\\sun}$ pc$^{-3}$.\n  Outside the inner two or three arcseconds, a constant mass-to-light ratio of $\\sim 2.2 \\pm 0.2$ is found to fit the observed line width measurements. The line width measurements of the center indicate the existence of either a central dark objec"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/9603056","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"}
