The data are analysed adopting a new simple and accurate formula for the signal, improving on the previous modeling of the detectors response, considering the possibility of background events. We perform several alternative analyses to quantify the relevance of various descriptions, approximations and biases. In particular, we study the effect of: omitting Baksan data or neglecting the background, using simplified formulae for the signal, modifying the fluence to","authors_text":"Francesco Vissani","cross_cats":["hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2014-09-16T17:38:07Z","title":"Comparative analysis of SN1987A antineutrino fluence"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1409.4710","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:c09b246178f3835c6320d06a0003e232f9a6603cd20480c2b39806b035d21893","target":"record","created_at":"2026-05-18T01:42:02Z","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":"625d542a303690a56dbacd6d8b5d24e5f0147baa23537ff8688e1dc7b29fe8e0","cross_cats_sorted":["hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2014-09-16T17:38:07Z","title_canon_sha256":"cd4dca67d42b71781a234e40f188371cd4145871e0ca29567dc638c90db03dbe"},"schema_version":"1.0","source":{"id":"1409.4710","kind":"arxiv","version":1}},"canonical_sha256":"0223372b67b929c336cd62bdcc069259a6594bf2e56da378e04daee9b7d2fdb2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0223372b67b929c336cd62bdcc069259a6594bf2e56da378e04daee9b7d2fdb2","first_computed_at":"2026-05-18T01:42:02.059163Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:42:02.059163Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"KlGX6yLU7jQvTxlq5WacKLsvgJrTzqCTi2K16uokhPyBqYvs4PWo5DUKl1r9rYAN1JS3JpbCreo/zIpb34bMDQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:42:02.059563Z","signed_message":"canonical_sha256_bytes"},"source_id":"1409.4710","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c09b246178f3835c6320d06a0003e232f9a6603cd20480c2b39806b035d21893","sha256:83426f5d8511d6f8f884658598e72751efbbcf0d24f3888489677d040abeb247"],"state_sha256":"d9aa600f72660ece03b34635bb8ea8b52d637393603e42a54d9bd2de31ca604f"}
