The projected mass profile of A 3408 was determined from the ICM temperature and the $\\beta$-model parameters obtained with ASCA, assuming that the hot gas is spherically symmetric and in hydrostatic equilibrium. The projected mass within an arc radius, $r_{\\rm arc}$, of 110 kpc is $M(r_{\\rm arc})=1.2^{+0.8}_{-0.4} \\times10^{13} \\MO$. This is 18 -- 45% of the mass previously derived from a lensing analysis by Campusano et al. (1998, AAA 069.160.189) without any X-ray information.\n  The primary"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0111017","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"}
