Removal of frequency-dependent interstellar medium (ISM) delays due to dispersion and scattering is a key issue in the detection process. Current timing algorithms routinely correct pulse times of arrival (TOAs) for time-variable delays due to cold plasma dispersion. However, none of the major pulsar timing groups correct for delays due to scattering from multi-path propagation in the ISM. Scattering introduces a frequency-dependent phase change in the si","authors_text":"Daniel Stinebring, Glenn Jones, Maura McLaughlin, Nipuni Palliyaguru, Paul Demorest","cross_cats":["astro-ph.HE","astro-ph.SR"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2015-11-13T02:12:06Z","title":"Correcting for Interstellar Scattering Delay in High-precision Pulsar Timing: Simulation Results"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1511.04139","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":"sha256:6b4e9774f90d9d0d014bd9188af0494d2b7d636fea9a1c4ee3c5f8fb34a2043f","target":"record","created_at":"2026-05-18T01:24:16Z","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":"5f8760e3b54161646b4fa06bad6c6658912c2ca0d21ec0cae658d74c73589bd4","cross_cats_sorted":["astro-ph.HE","astro-ph.SR"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2015-11-13T02:12:06Z","title_canon_sha256":"b3b5637f2f58999a764a22c258d1220ee37de701abe472cfe04a610b5780c547"},"schema_version":"1.0","source":{"id":"1511.04139","kind":"arxiv","version":1}},"canonical_sha256":"9a15db689a8e2757deed4e8a9442c4e0675cd510c5567ac23a17805bc9d2c02e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9a15db689a8e2757deed4e8a9442c4e0675cd510c5567ac23a17805bc9d2c02e","first_computed_at":"2026-05-18T01:24:16.017669Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:24:16.017669Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"DnYkASblSzcQFX4xwg7bRovibBaUYIesUXdq6D1GPzcYvhrfSvbwlQRgu2sWi82rLHzK2IKQl1Y3JEVYUc1+Bw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:24:16.018296Z","signed_message":"canonical_sha256_bytes"},"source_id":"1511.04139","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6b4e9774f90d9d0d014bd9188af0494d2b7d636fea9a1c4ee3c5f8fb34a2043f","sha256:92d3485a31b4c303a237008a71dfca359422da75dd8f35a73392731e0bd47e73"],"state_sha256":"2a4d16a010d21ea7dcbadce9d054b6b1f02066e1261cd2734101a6cd3cf49266"}
