The first method called FLens integrates an inpainting concept to invert the shear field with possible gaps, and a multi-scale entropy denoising procedure to remove the noise contained in the final reconstruction, that arises mostly from the random intrinsic shape of the galaxies. The second and third methods are based on a model of the density field made of a multi-scale grid of radial basis functions. In one case, the model parameters are computed with a linear inversion involving a s","authors_text":"Eric Jullo, Jean-Paul Kneib, Mathilde Jauzac, Sandrine Pires","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2013-09-23T07:29:29Z","title":"Weak Lensing Galaxy Cluster Field Reconstruction"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1309.5718","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":"sha256:96ea2e245ff7f96691e872c0cfb384205d9646399893ec4f2fdf8db1592a5e5e","target":"record","created_at":"2026-05-18T01:47:34Z","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":"3a9b5c49c7f72ab17bf852cad5064141ce4f6cefd730ac7e5ec69950917fab2e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2013-09-23T07:29:29Z","title_canon_sha256":"b96cc5308211ea461e83e47fc926474e448dee32dd51c124d6e3a10dfcc02d96"},"schema_version":"1.0","source":{"id":"1309.5718","kind":"arxiv","version":2}},"canonical_sha256":"477782913eaa0e9b2293875d7b223bc0fecca41073d3e52ab34952ebdf21a9d4","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"477782913eaa0e9b2293875d7b223bc0fecca41073d3e52ab34952ebdf21a9d4","first_computed_at":"2026-05-18T01:47:34.412710Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:47:34.412710Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"gPAwGlsUwdxfbTlPCeYP3WGwXbZk5MFLVEA770IlRLztMGRK1aA1pT83laQI8zFgK9AmE2bBJP/k3z1aKRXtAg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:47:34.413335Z","signed_message":"canonical_sha256_bytes"},"source_id":"1309.5718","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:96ea2e245ff7f96691e872c0cfb384205d9646399893ec4f2fdf8db1592a5e5e","sha256:4466aed5b42713724b7abe497fc94eb6b5bd0288d57fc441a5bc2f1fb1cad788"],"state_sha256":"cf177d5274182e9e1bbcd482158fd5750ccb66590f83e72f83c47759bcf10883"}
