This dataset mirrors the complete ESA Gaia Data Release 3 gaia_source bulk-download table. It contains one record for every published Gaia source and all 152 columns served by ESA, including source identifiers, astrometry, photometry, observing statistics, quality fields, classifications, and astrophysical parameters.

Each of ESA's 3,386 compressed ECSV shards is retained as one dataset configuration. The configuration name is the source filename stem verbatim. Columns retain ESA's names, order, ECSV scalar dtypes, units, descriptions, nulls, and row order. The full source ECSV header is embedded in every Parquet artifact. The twelve fields declared as bool by ESA remain Arrow Boolean; other fields remain their declared integer, floating-point, or string types.

Publication status

Upload is in progress. The source census contains 3,386 shards, totaling 753,025,661,884 compressed source bytes and 1,811,709,771 catalogue rows. Each source shard was verified against ESA's published MD5 before conversion. This card will report uploaded file and byte totals as verified Hub copies land.

Artifacts use astro-legacy-archive/statistical-product schema 1.3.0. Every artifact records the source URL, compressed-source SHA-256 and size, the verbatim ECSV header, structured field and unit evidence, and regeneration provenance pinned to a full repository commit. Conversion and verification are streaming; no whole catalogue or whole shard table is materialised.
