The spectro-photometric signal is not affected only by image movement and deformation due to wavefront error but also by electrical variation in the detector system. These time-variation components, coupled to the transit signal, distort the measurements of atmospheric composition in transit spectroscopy. Here we propose a new concept for improvement of spectro-photometric accuracy through the calibration of the time-vari","authors_text":"Shohei Goda, Taro Matsuo","cross_cats":["astro-ph.IM"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2018-10-23T07:39:50Z","title":"A New Method for Calibration of Gain Variation in Detector System"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1810.09702","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":"sha256:9e503e772a04e217f4d0759ec945ffb1208dd7a1b4ad9439ec60519e3446effb","target":"record","created_at":"2026-05-17T23:59:04Z","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":"48f9c5809149f920295e997b7f3614139f85a208496c6673889779774cc6d1e2","cross_cats_sorted":["astro-ph.IM"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2018-10-23T07:39:50Z","title_canon_sha256":"a73a10bf4f68a01d3429f53c51f26b9ef0a551b050c5e75c9caf144918aa58b7"},"schema_version":"1.0","source":{"id":"1810.09702","kind":"arxiv","version":2}},"canonical_sha256":"2d4174ec41abbfa0608ab5b089a2d81641093c75d95cca1c8c7c1a85838874e1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2d4174ec41abbfa0608ab5b089a2d81641093c75d95cca1c8c7c1a85838874e1","first_computed_at":"2026-05-17T23:59:04.415874Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:59:04.415874Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Ag88By8giOBAjlI/p6wSmKkH8c/5kIneQF9/atI2zUQyIa88ksTS2znCd7EDTnNKvaDVMg1B0EoLD7h8ikTAAw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:59:04.416247Z","signed_message":"canonical_sha256_bytes"},"source_id":"1810.09702","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9e503e772a04e217f4d0759ec945ffb1208dd7a1b4ad9439ec60519e3446effb","sha256:ab24baa62a5f99112193a39856b407d0269c049a1046b4b6ca3b992784fabb04"],"state_sha256":"d721989ebc79b4695ede397b350132a0d71166addf6af14f4f2c2e667e7bc618"}
