Euclid Q1 Overview

Euclid Data Explorer

Overview

Euclid Quick Release 1 (Q1) consists of approximately 35 TB of imaging, spectroscopy, and catalogs covering four non-contiguous fields: Euclid Deep Field North (22.9 sq deg), Euclid Deep Field Fornax (12.1 sq deg), Euclid Deep Field South (28.1 sq deg), and LDN1641. If you use Euclid Q1 data from the IRSA archive, please cite the journal article, cite the appropriate Digital Object Identifier (see below), and include the following acknowledgement: "This work has made use of the Quick Release (Q1) data from the Euclid mission of the European Space Agency (ESA)."
