A hybrid air shower reconstruction technique is employed to improve accuracies in determination of arrival directions and primary energies of cosmic rays using both FD and SD data. The energy spectrum presented here is in agreement with our previously published spectra and the HiRes results.","authors_text":"A.L.Sampson, A.Oshima, A.Taketa, B.G.Cheon, B.K.Shin, B.T.Stokes, C.C.H.Jui, D.C.Rodriguez, D.Ikeda, D.Ivanov, D.Oku, D.R.Bergman, D.Ryu, E.Barcikowski, E.J.Cho, E.Kido, F.Kakimoto, F.Shibata, F.Urban, G.B.Thomson, G.Rubtsov, G.Vasiloff, H.B.Kim, H.Fujii, H.Ito, H.Kawai, H.K.Kim, H.Ohoka, H.Sagawa, H.Shimodaira, H.Tanaka, H.Tokuno, H.Ukai, H.Yamaoka, H.Yoshii, I.H.Park, I.Myers, I.Tkachev, J.Chiba, J.D.Smith, J.H.Kim, J.I.Shin, J.Lan, J.N.Matthews, J.P.Lundquist, J.W.Belz, J.Yang, K.Hayashi, K.Hibino, K.Hiyama, K.Honda, K.Ikuta, K.Kadota, K.kasahara, K.Kitamoto, K.Kobayashi, K.Kuramoto, K.Martens, K.Miyata, K.Nagasawa, K.Oki, K.Tanaka, K.Tsutsumi, K.Yamazaki, L.M.Scott, M.Allen, M.Chikawa, M.Fukushima, M.Minamino, M.Ohnishi, M.Ono, M.S.Pshirkov, M.Takeda, M.Takita, M.Tanaka, N.Hayashida, N.Inoue, N.Sakurai, O.Kalashev, P.D.Shah, P.Sokolsky, P.Tinyakov, R.Aida, R.Anderson, R.Azuma, R.Cady, R.Ishimori, R.W.Springer, R.Yamane, R.Zollinger, S.A.Blake, S.B.Thomas, S.I.Lim, S.Iwamoto, S.Kawakami, S.Kawana, S.Kitamura, S.Machida, S.Nagataki, S.Ogio, S.Ozawa, S.R.Stratton, S.Suzuki, S.Troitsky, S.Udo, S.W.Nam, S.Yoshida, S.Y.Roh, T.Abu-Zayyad, T.Fujii, T.Fukuda, T.Iguchi, T.Ishii, T.Kanbe, T.Matsuda, T.Matsuura, T.Matsuyama, T.Nakamura, T.Nonaka, T.Okuda, T.Shibata, T.Shirahama, T.Stroman, T.Tomida, T.Wong, V.Kuzmin, W.Hanlon, W.R.Cho, X.Zhou, Y.Hayashi, Y.J.Kwon, Y.Kitamura, Y.Kobayashi, Y.Kondo, Y.Murano, Y.Takahashi, Y.Tameda, Y.Tsunesada, Y.Tsuyuguchi, Y.Uchihori, Y.Wada, Y.Yamakawa, Y.Yoneda, Z.Zundel","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2013-05-31T00:13:07Z","title":"Energy Spectrum of Ultra-High Energy Cosmic Rays Observed with the Telescope Array Using a Hybrid Technique"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1305.7273","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:a97e6f351791e9714a5edbe65538e7c8b49e15d49aae4f7671a10d08d2314173","target":"record","created_at":"2026-05-18T03:22:07Z","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":"0a7fa8c28e611b250ca8df9c5798401fb54016a51427abaa7dc45652dc0b5ea9","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2013-05-31T00:13:07Z","title_canon_sha256":"4212bb0406c5e899363c08ff8d41337347a5c5514df61d081d31550f8974dca1"},"schema_version":"1.0","source":{"id":"1305.7273","kind":"arxiv","version":1}},"canonical_sha256":"e544d5b89088d6e7e90fca4aba30e61fe20e3bfc186f26a11638dc343757f248","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e544d5b89088d6e7e90fca4aba30e61fe20e3bfc186f26a11638dc343757f248","first_computed_at":"2026-05-18T03:22:07.343725Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:22:07.343725Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"WJhHk/Ol4MqLzsjWtv0GGYi8dgCFn7VIyaqNoehi7VwBVuLhxbfSu1KC7iZVeqQEAZ+KjqIf6G4OA3slQRBABA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:22:07.344511Z","signed_message":"canonical_sha256_bytes"},"source_id":"1305.7273","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a97e6f351791e9714a5edbe65538e7c8b49e15d49aae4f7671a10d08d2314173","sha256:a7158d0ddb92e39c5396097cd9b1ac997a56f3f8a3864ffe6a9144c1c49fd3f7"],"state_sha256":"4d2816c34400b81dd44bd9ed1fa04d150b0965890e7a6bd8ca35b715dc2aeaa5"}
