A Catalog of Very Large Array Sky Survey Epoch 1 Quick Look Components, Sources, and Host Identifications
Bibliographic record
Abstract
Abstract We announce here the public availability of a catalog of ν ∼ 3 GHz Quick Look observations from the first epoch of the Very Large Array Sky Survey. The catalog consists of three distinct and linkable tables, namely (a) the detected radio components, (b) the host identifications with total source properties for single-component, and close double/triple radio sources (angular separations of <10″), and (c) the Quick Look image metadata. Given the Quick Look images are limited in quality, we include data reliability flagging to improve the scientific usability of this catalog. Using our recommended quality flags, this catalog contains 1.7 × 10 6 unique radio components with S 3 GHz ≳ 1 mJy beam −1 , and 6.2 × 10 5 host IDs (including 20,000 close-double and triple radio sources) reliably detected across the entire sky at δ > −40°. The catalog and an associated User Guide have been produced as part of the Canadian Initiative for Radio Astronomy Data Analysis, and are available at https://cirada.ca/catalogues .
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
