The array will be the first true radio camera, outputting science-ready image data over the 0.7 - 2 GHz frequency range with a spatial resolution of 3.5 arcsec. With 2000 x 5 m dishes, the DSA-2000 will have an equivalent point-source sensitivity to SKA1-mid, but with ten times the survey speed. The DSA-2000 is envisaged as an all-sky survey instrument complementary to the ngVLA, and as a counterpart to the LSST (optical), SPHEREx (near-infrared) and SRG/eROSITA (X-ray) all"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"Central claim unavailable from malformed reader payload.","source":"verdict.strongest_claim","status":"machine_extracted","claim_id":"C1","attestation":"unclaimed"},{"kind":"weakest_assumption","text":"Load-bearing assumption unavailable from malformed reader payload.","source":"verdict.weakest_assumption","status":"machine_extracted","claim_id":"C2","attestation":"unclaimed"},{"kind":"one_line_summary","text":"Pith review generated a malformed one-line summary.","source":"verdict.one_line_summary","status":"machine_extracted","claim_id":"C3","attestation":"unclaimed"},{"kind":"headline","text":"A proposed 2000-dish radio array would survey the sky ten times faster than the next flagship facility by outputting calibrated images, not visibilities.","source":"verdict.pith_extraction.headline","status":"machine_extracted","claim_id":"C4","attestation":"unclaimed"}],"snapshot_sha256":"927681eb52dc7c3968cf43ea7a4650c06129589d0a6749dfde46f1015f2d283c"},"source":{"id":"1907.07648","kind":"arxiv","version":1},"verdict":{"id":"be429cec-2c2f-4050-9185-f5c1f678a1ac","model_set":{"reader":"claude-opus-4-7"},"created_at":"2026-05-08T23:10:43.512969Z","strongest_claim":"Central claim unavailable from malformed reader payload.","one_line_summary":"Pith review generated a malformed one-line summary.","pipeline_version":"pith-pipeline@v0.9.0","weakest_assumption":"Load-bearing assumption unavailable from malformed reader payload.","pith_extraction_headline":"A proposed 2000-dish radio array would survey the sky ten times faster than the next flagship facility by outputting calibrated images, not visibilities."},"integrity":{"clean":true,"summary":{"advisory":0,"critical":0,"by_detector":{},"informational":0},"endpoint":"/pith/1907.07648/integrity.json","findings":[],"available":true,"detectors_run":[],"snapshot_sha256":"c28c3603d3b5d939e8dc4c7e95fa8dfce3d595e45f758748cecf8e644a296938"},"references":{"count":18,"sample":[{"doi":"","year":1995,"title":"1995, ApJ, 450, 559 – ‘The FIRST Survey: Faint Images of the Radio Sky at Twenty Centimeters’","work_id":"4d17c09f-7191-4060-bb93-2ce8cfae64fb","ref_index":1,"cited_arxiv_id":"","is_internal_anchor":false},{"doi":"","year":2017,"title":"Bhatnagar, S.; Cornwell, T.
