Constraints on the TeV fluence and the energy spectrum are now derived using additional data from a scaler system that recorded the rate of signals from the Milagrito photomultipliers. This analysis shows that if emission from GRB970417a has been observed, it must contain photons with energies above 650 GeV. Some consequences of this observation are discussed.","authors_text":"A.Falcone, A.I.Mincer, A.J.Smith, A.Shoup, B.L.Dingus, B.Shen, C.M.Hoffman, C.Sinnis, D.A.Williams, D.Berley, D.E.Dorfan, D.Evans, D.G.Coyne, F.W.Samuelson, G.B.Yodh, G.Gisler, G.W.Sullivan, I.Leonor, J.A.Goodman, J.E.McEnery, J.F.McCullough, J.M.Ryan, K.Wang, L.A.Kelley, L.Fleysher, M.F.Morales, M.L.Chen, M.M.Gonzalez Sanchez, M.O.Wascko, P.Nemethy, R.Atkins, R.Fleysher, R.S.Miller, R.W.Ellsworth, S.Hugenberger, S.Klein, S.Westerhoff, T.J.Haines, T.Tumer, T.Yang, W.Benbow","cross_cats":[],"headline":"","license":"","primary_cat":"astro-ph","submitted_at":"2002-07-06T14:21:34Z","title":"The high-energy gamma-ray fluence and energy spectrum of GRB 970417a from observations with Milagrito"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0207149","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:8c34fd47c7ab95505248596059d384be2f59ef718c4295e4bcc4fd8d5f6ceb8a","target":"record","created_at":"2026-07-04T15:32:01Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"3c7d942ad24c86a84677281b483c6177791c4aa6cb5b7cefc16d9a3f5976251f","cross_cats_sorted":[],"license":"","primary_cat":"astro-ph","submitted_at":"2002-07-06T14:21:34Z","title_canon_sha256":"5ded6abe785d95f4938f8551b8cb7fc4fb076b7e90d57d078888f4693342152b"},"schema_version":"1.0","source":{"id":"astro-ph/0207149","kind":"arxiv","version":1}},"canonical_sha256":"61bbd77e91d5a58d7af596faf41a4b15c40c0df08fcb3d5ffcf1db48eb2ae14a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"61bbd77e91d5a58d7af596faf41a4b15c40c0df08fcb3d5ffcf1db48eb2ae14a","first_computed_at":"2026-07-04T15:32:01.659523Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T15:32:01.659523Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"35jwvcP8awctBC+2QcFrGqbq0XCUqTBOFa7ngC/8FiokRmFYpfMB8WpN8Renfh7aqaucVrrEunp6fVc+a6iKCQ==","signature_status":"signed_v1","signed_at":"2026-07-04T15:32:01.660068Z","signed_message":"canonical_sha256_bytes"},"source_id":"astro-ph/0207149","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8c34fd47c7ab95505248596059d384be2f59ef718c4295e4bcc4fd8d5f6ceb8a","sha256:7a989a812608b0836043898b98dd8b9389b5824193e42a02febc275be09e9b50"],"state_sha256":"e4dadaa3bc18c4ab0573451b8f16f94a5afbd6b85228ca50f0630e33b2d147f4"}
