The whole spectrum of both objects can be explained by thermal emission. The luminosities found for RXJ1720.1+2638 and Abell267 in the 2-10 keV band are 6.20^{+0.04}_{-0.02}\\times10^{44} and 3.90^{+0.10}_{-0.11}\\times10^{44} cgs, respectively. The radial profiles show a cool core nature for the non-fossil system RXJ1720.1+2638, while Abell267 shows a constant behaviour of temperature with radius. Metallicity profiles have also been produced, but no evidence of any gradient w"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1302.5438","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"}
