It currently provides implementations or interfaces for the Iterative Bayes, Singular Value Decomposition, and TUnfold methods, as well as bin-by-bin and matrix inversion reference methods. Common tools provide covariance matrix evaluation and multi-dimensional unfolding. A test suite allows comparisons of the performance of the algorithms under different truth and measurement models. Here I outline the package, the unfolding methods, and some experience of their use.","authors_text":"Tim Adye","cross_cats":["hep-ex"],"headline":"","license":"http://creativecommons.org/licenses/by/3.0/","primary_cat":"physics.data-an","submitted_at":"2011-05-05T19:59:50Z","title":"Unfolding algorithms and tests using RooUnfold"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1105.1160","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":"sha256:530b7cf55df900df98493002117cfa3bf82576927f8e2e2fd0608ab2e3aa9ea7","target":"record","created_at":"2026-05-18T04:06:46Z","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":"f60492a2eb2acab96838bb69db3059c25004cc7993b5d90204fdf2a68c4a0962","cross_cats_sorted":["hep-ex"],"license":"http://creativecommons.org/licenses/by/3.0/","primary_cat":"physics.data-an","submitted_at":"2011-05-05T19:59:50Z","title_canon_sha256":"3f6618ae9ecd2b577ba4791dbf1b9ebdbe224acae8d282079be0de1db5757c7e"},"schema_version":"1.0","source":{"id":"1105.1160","kind":"arxiv","version":1}},"canonical_sha256":"6f53d29674c14e4072bfb750886b503cbc8fb7d47dc9df9394036e051adc19a7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6f53d29674c14e4072bfb750886b503cbc8fb7d47dc9df9394036e051adc19a7","first_computed_at":"2026-05-18T04:06:46.164343Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:06:46.164343Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"HlKrtZD4DU3HDIS5cb7S0PP6gNW/cjjN+zNMDvx2Es0BINBa2Hk+wJyncDo0egVQL6QUD9nVYoxyC0R9XXfNCw==","signature_status":"signed_v1","signed_at":"2026-05-18T04:06:46.164922Z","signed_message":"canonical_sha256_bytes"},"source_id":"1105.1160","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:530b7cf55df900df98493002117cfa3bf82576927f8e2e2fd0608ab2e3aa9ea7","sha256:7f95eedd4f50dc69b04e735482e27c9fad6b9e3eb4cf5b027ac23e50b7607845"],"state_sha256":"a8bcefe563f256af963b0b04c307cc49d0e7dea80df152db4204dbe40ecc2af8"}
