Clusters can be roughly grouped into two categories -- relaxed and non-relaxed -- and a proper characterisation of the dynamical state of these systems is of crucial importance both for astrophysical and cosmological studies.\n  In this paper we investigate the use of a number of morphological parameters (Gini, $M_{20}$, Concentration, Asymmetry, Smoothness, Ellipticity and Gini of the second order moment, $G_{M}$) introduced to automatically cl","authors_text":"Benne Holwerda, Chiara Ferrari, Garry Angus, Kurt van der Heyden, Viral Parekh","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/3.0/","primary_cat":"astro-ph.CO","submitted_at":"2014-11-24T16:50:58Z","title":"Morphology parameters: substructure identification in X-ray galaxy clusters"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1411.6525","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":"sha256:4f0dcefd03a3724fe13629482fcf3d3533791fe2587b0da49f87ae0341562c13","target":"record","created_at":"2026-05-18T02:25:18Z","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":"39eafb23318d4eb16ddbf05c529915d83169d94efba21d7d357da546af71dd6b","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/3.0/","primary_cat":"astro-ph.CO","submitted_at":"2014-11-24T16:50:58Z","title_canon_sha256":"925f5d74fa4eea5e918920b05b07732fad5ca8e35ed3cbc22d02ce292bd4cc47"},"schema_version":"1.0","source":{"id":"1411.6525","kind":"arxiv","version":1}},"canonical_sha256":"7e3cdb89f2129308c038c09605c40cd521c6e73cb83ab2b1369bf19012954330","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"7e3cdb89f2129308c038c09605c40cd521c6e73cb83ab2b1369bf19012954330","first_computed_at":"2026-05-18T02:25:18.418310Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:25:18.418310Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"5x5F24a9yJCbCA3tPaitvaCkajt+r8uQqSpcbZtjmiWMxJ3rx+w/YzovTpGbtasKgWLjr9rBRX6lJ0fPSC/3Dw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:25:18.418670Z","signed_message":"canonical_sha256_bytes"},"source_id":"1411.6525","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:4f0dcefd03a3724fe13629482fcf3d3533791fe2587b0da49f87ae0341562c13","sha256:463a88b4fe8ec4d6525115f659449db70e558074a7788e9b58d56d493618c6dd"],"state_sha256":"b6d08fe0125f4b23175c3698694a57e5f9e43037953c6f2865bc06595a6ff0b6"}
