Using published timing data of the observed bursts, we show that Poissonian statistics are not a good description of this random process. As an alternative we suggest to describe the intervals between bursts with a Weibull distribution with a shape parameter smaller than one, which allows for the clustered nature of the bursts. We quantify the amount of clustering using the parameters of the Weibull distribution and discuss the consequences that it has for the detection probabilities of future observations and ","authors_text":"Hao-Ran Yu, Niels Opperman, Ue-Li Pen","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2017-05-13T20:08:07Z","title":"On the non-Poissonian repetition pattern of FRB121102"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1705.04881","kind":"arxiv","version":2},"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":"sha256:9234df16384bc5dd0e59afbf2096dd451dffc48c1318927ff762a64f9cc874e1","target":"record","created_at":"2026-05-18T00:15:52Z","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":"b476eaf5fad1d0c1bb615e323c27ebce4293bbc5a8680c407a716f4656a6ef14","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2017-05-13T20:08:07Z","title_canon_sha256":"ec148ee11b38ce70e7e33694c6377cf728907698ab60059f118869b436101cd1"},"schema_version":"1.0","source":{"id":"1705.04881","kind":"arxiv","version":2}},"canonical_sha256":"c618e1802563ec4f4f022084b81b5853033f69c01e6e6f5b27daea06206e85f4","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c618e1802563ec4f4f022084b81b5853033f69c01e6e6f5b27daea06206e85f4","first_computed_at":"2026-05-18T00:15:52.569276Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:15:52.569276Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"tIR6mbj9v48/TOa1Pn9GYR9fhkrj3OUGCj7P948ryVto4zsGGf/SSE0Zb//h7DN+6WNJyjFzLavhqWCj+HMwAA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:15:52.569854Z","signed_message":"canonical_sha256_bytes"},"source_id":"1705.04881","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9234df16384bc5dd0e59afbf2096dd451dffc48c1318927ff762a64f9cc874e1","sha256:85827c083da11697da0105833d90cea76c6b24803071ff5910482380cdaf5f52"],"state_sha256":"19736f259165fe3e54e7905881ccaebb70d4d4823706415450e2edb5e48581ad"}
