We initially detect 7 candidate sources with signal-to-noise ratios (SNRs) between 3.0 and 3.5 and 4 candidate sources with SNR > 3.5. Simulations suggest that on average in a map this size one expects 1.6 false positive sources for SNR > 3.5 and 4.5 for 3 < SNR < 3.5. Flux boosting in maps is a well known effect and we have developed a simple Bayesian prescription for estimating the unboosted flux distribution and used this method to determine the best flux estimates o","authors_text":"Colin Borys, Douglas Scott, Kristen Coppin, Mark Halpern, Scott Chapman","cross_cats":[],"headline":"","license":"","primary_cat":"astro-ph","submitted_at":"2004-12-10T21:02:55Z","title":"An 850-micron SCUBA map of the Groth Strip and reliable source extraction"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0412267","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":"sha256:209a3c87f7d066b110d0065ffabda937e1abf77ce3570127f0c48f7ec9ddfd40","target":"record","created_at":"2026-05-18T01:07:31Z","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":"d1966b4746871a4d2b5dd3f6103c7e54cf2363887c72e80f69278a832571c4b7","cross_cats_sorted":[],"license":"","primary_cat":"astro-ph","submitted_at":"2004-12-10T21:02:55Z","title_canon_sha256":"e999e4597999e899b8a0203e37442a473bfb76426ad41fa022be611a0b597b38"},"schema_version":"1.0","source":{"id":"astro-ph/0412267","kind":"arxiv","version":1}},"canonical_sha256":"332fd17cda51b9ba66a6eb172c34994b4219b2c5f241d4dbb3fde39dd767516f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"332fd17cda51b9ba66a6eb172c34994b4219b2c5f241d4dbb3fde39dd767516f","first_computed_at":"2026-05-18T01:07:31.806675Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:07:31.806675Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"R7/zgUYws4W6RKiKwzU5hzeLtJWQ0ds9jre7GJy/a/2A31KzYWLxXP/iFu4DnJ3PurINqID36sDheu1HOVW0Cw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:07:31.807292Z","signed_message":"canonical_sha256_bytes"},"source_id":"astro-ph/0412267","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:209a3c87f7d066b110d0065ffabda937e1abf77ce3570127f0c48f7ec9ddfd40","sha256:36131c15657cf24803be03a67186a0f064472e8a7c7e772c7b42a23f358393b4"],"state_sha256":"0deff631cd7990119412b66d138f028a01c0a4313379d7d4b180379f9a88af24"}
