The first one is related to one claim of \\citep{Donato} D09, namely: is the DM surface density (DMsd) a constant universal quantity, equal to $\\log{(\\rm \\Sigma/M_\\odot pc^{-2})}=2.15 \\pm 0.2$, or does it depend on the baryon surface density of the system? The second one, is based on a MOND prediction that for HSBs the DMsd is constant, and equal to $\\log{(\\rm \\Sigma/M_\\odot pc^{-2})}=2.14$, while for LSBs the surface density is not constant and takes values that are smaller than for HSBs and D09 prediction \\citep{Milgr","authors_text":"Antonino Del Popolo","cross_cats":["astro-ph.GA"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.CO","submitted_at":"2023-03-29T13:06:08Z","title":"SPARC HSBs, and LSBs, the surface density of dark matter haloes, and MOND"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2303.16658","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:b9713856751a46050e5ca557f6c492b90f367dcabf72b2ab695f9a5758e1b8d2","target":"record","created_at":"2026-07-05T05:56:09Z","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":"3daa917cfb402d63b68ab7ec17f3f158245646a0600dfddf9c890319109247b0","cross_cats_sorted":["astro-ph.GA"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.CO","submitted_at":"2023-03-29T13:06:08Z","title_canon_sha256":"acf9d21d887005c8c8c3ed51974633a343fd17fbf3cdf708fb0bf0492df3d84e"},"schema_version":"1.0","source":{"id":"2303.16658","kind":"arxiv","version":1}},"canonical_sha256":"10a81ef3f4b5c05134f2bb4a359bcf74fb16167e5fd660b9da0b56e18b756c36","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"10a81ef3f4b5c05134f2bb4a359bcf74fb16167e5fd660b9da0b56e18b756c36","first_computed_at":"2026-07-05T05:56:09.042631Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:56:09.042631Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ln2QcteE8PQe0Ikejw7eiQ2Yh9kYiRqjKJEL0k9tibsSJ6DiEW1xuUT2SYacJNJ+r8g+t+qAZ6mdT5tKI1rOAQ==","signature_status":"signed_v1","signed_at":"2026-07-05T05:56:09.043004Z","signed_message":"canonical_sha256_bytes"},"source_id":"2303.16658","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b9713856751a46050e5ca557f6c492b90f367dcabf72b2ab695f9a5758e1b8d2","sha256:9914e9176ac0dc6fae54c60dbbf555da6c9e258dd873e1448623faefa0ccfe94"],"state_sha256":"1103d91cfc89e18229f4aeb547b6aaf62454c1c047e9239ae881ff9567ad0be1"}
