We confirm the $\\Gamma_0$ - $E_{\\gamma,\\rm iso}$ correlation by Liang et al. (2010), and the $\\Gamma_0$ - $L_{\\gamma,\\rm iso}$ correlation by L{\\\"u} et al. (2012). Furthermore, we find correlations between $\\Gamma_0$ and the beaming corrected $\\gamma$-ray energy ($E_{\\gamma}$) and mean $\\gamma$-ray luminosity ($L_{\\gamma}$). By also including the kinetic energy of the afterglow, we find rough corre"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1612.06586","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"}
