Euclid Q1 Level 2 VIS Calibrated Imaging Data

Euclid launched in July 2023 as a European Space Agency (ESA) mission with involvement by the National Aeronautics and Space Administration (NASA). The Euclid mission provides space-based imaging and spectroscopy as well as supporting ground-based imaging.

The Level 2 calibrated VIS imaging data represent a subset of the data products released as part of Euclid Quick Release 1 (Q1). These images are provided in the VIS band and cover over 60 square degrees on the sky across four non-contiguous regions: 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.

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.

欧几里得（Euclid）任务于2023年7月发射，是欧洲空间局（European Space Agency, ESA）主导、美国国家航空航天局（National Aeronautics and Space Administration, NASA）参与的航天探测项目。
欧几里得任务可提供天基成像与光谱观测服务，并支持地基成像观测。
经过校准的二级VIS成像数据（Level 2 calibrated VIS imaging data）是欧几里得快速发布1号（Euclid Quick Release 1, Q1）数据产品的子集。该系列图像采用VIS波段采集，覆盖天区中4个非连续区域，总面积逾60平方度，分别为：北欧几里得深场（22.9平方度）、天炉座欧几里得深场（12.1平方度）、南欧几里得深场（28.1平方度）以及LDN1641。
本数据集及相关服务由美国加州理工学院依据与美国国家航空航天局签订的合同运营的IPAC下属红外科学档案馆（Infrared Science Archive, IRSA）提供发布。
