In this contribution, results of first studies on the location accuracy are presented. These studies are based on a toy Monte Carlo simulation of a typical CTA-South array layout, taking into account the expected trigger rates of the different CTA telescope types and the gamma-ray spectrum of the simulated source. With this simulation code it is possible to study the location accur","authors_text":"Alexander Ziegler, Christopher van Eldik, David Berge, Johannes Veh, Markus Gaug (for the CTA Consortium), Stefan Eschbach","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2015-09-07T10:23:03Z","title":"Studies towards an understanding of global array pointing for the Cherenkov Telescope Array"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1509.01973","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":"sha256:083a6ed3b0350327bf2152e7e40263978e05b60badc28a6462f9697213c57898","target":"record","created_at":"2026-05-18T01:33:50Z","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":"03433d2871f469f9a0dabb837fa4bb6960987c964a1fa1c728c5b091dc2b0de4","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.IM","submitted_at":"2015-09-07T10:23:03Z","title_canon_sha256":"5a8e0463d231478bedce48e9d16edd77b029594c0cc7161f3231b877de0cd551"},"schema_version":"1.0","source":{"id":"1509.01973","kind":"arxiv","version":1}},"canonical_sha256":"1bdc37b607f29a4c6d6f839cb25413b4d8fc75cb708a28270a6d4cd9709a9dbc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1bdc37b607f29a4c6d6f839cb25413b4d8fc75cb708a28270a6d4cd9709a9dbc","first_computed_at":"2026-05-18T01:33:50.008534Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:33:50.008534Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"lDBCcEBCp8qiW832Cy6GqRwZvHkRY+2BeSFug8dhJBe8OiI0TIBVaYx6Mv8dVZuF0H+7MmjOvaZgN80dC4yuBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T01:33:50.009196Z","signed_message":"canonical_sha256_bytes"},"source_id":"1509.01973","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:083a6ed3b0350327bf2152e7e40263978e05b60badc28a6462f9697213c57898","sha256:2ea51ad83aadec23d6ab387ddd0d6cba9a0fc7570f3ad82d03d9654a368ffd89"],"state_sha256":"e7af427466dee32d8bbf4724fa16bd16453cac9469f5c973b1d0acb021202a7c"}
