Euclid DR1 MER Catalog - Deep Survey

Euclid Data Release 1 (DR1) is the first major public data release from the European Space Agency's Euclid mission. DR1 includes approximately 1.8 PB of imaging, catalogs, and spectra covering approximately 1,900 square degrees of the Euclid Wide Survey, as well as observations of the Euclid Deep Fields, calibration fields, and other fields observed before the start of the nominal survey.

DR1 supersedes the earlier Euclid Quick Release 1 (Q1) and is being released in two stages. The first, DR1-Foundation, was released on November 12, 2026, and includes most of the DR1 data products. The complete DR1 release, expected in mid-2027, will add higher-level science products for galaxy clustering and weak lensing studies.

This dataset or service is made available by the Infrared Science Archive (IRSA) at IPAC, which is operated by the California Institute of Technology under contract with the National Aeronautics and Space Administration.
