In this work, we introduce Coport, a novel public code specifically designed for covariant polarized ray-tracing radiative transfer computations in any spacetime. Written in Julia, Coport includes an interface for visualizing numerical results obtained from HARM, a publicly available implementation of the general relativistic magnetohydrodynamics code. We validate the precision of our code by comparing its outputs with the results f","authors_text":"Bin Chen, Jiewei Huang, Liheng Zheng, Minyong Guo","cross_cats":["astro-ph.IM","gr-qc"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.HE","submitted_at":"2024-07-15T04:17:43Z","title":"Coport: A New Public Code for Polarized Radiative Transfer in a Covariant Framework$^\\spadesuit$"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2407.10431","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":"sha256:844372aad067cfb076c6cdef1e57aff7d271c85313d2ba5faa1f916d9da9989f","target":"record","created_at":"2026-07-05T09:30:18Z","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":"e7d64ee54f4a5f7bd92ffb79c27b0cb33a23bc2fce1276d25723b8f7cf31dd18","cross_cats_sorted":["astro-ph.IM","gr-qc"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.HE","submitted_at":"2024-07-15T04:17:43Z","title_canon_sha256":"c9103118d6fe9a636668d5b38da586ab767300d28915b37fd15dd162ca9c34e2"},"schema_version":"1.0","source":{"id":"2407.10431","kind":"arxiv","version":2}},"canonical_sha256":"ae578ad65a37782f50ee583e3ee01fe9bc916d182139d60e29debb82b98dbc0c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ae578ad65a37782f50ee583e3ee01fe9bc916d182139d60e29debb82b98dbc0c","first_computed_at":"2026-07-05T09:30:18.778498Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T09:30:18.778498Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"U5XkNl5QwHySNd/JoWzIVGzWQ7zv/6iUyElVvG05SdAREvOFLWk8jV9V5m7ptdiQfDC3dvIKJcPVgndWQawfDA==","signature_status":"signed_v1","signed_at":"2026-07-05T09:30:18.778984Z","signed_message":"canonical_sha256_bytes"},"source_id":"2407.10431","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:844372aad067cfb076c6cdef1e57aff7d271c85313d2ba5faa1f916d9da9989f","sha256:01fccbfca1065692170aa7ed69ee5dc05927b498333b38a7559d4efddd46e7a8"],"state_sha256":"29488dc64ea96bd952c0cd91d5ef7d393d7067245d8e8934c7750db28241920f"}
