Description

The European Space Agency (ESA) Euclid Quick Release 1 (Q1) consists of some 35 TB of single-epoch imaging, spectroscopy, and catalogues covering three Euclid Deep Fields of combined size 63 deg2 on the sky. The data are available at the ESAC Science Data Centre (ESDC) through the Euclid Science Archive as well as the ESA Datalabs e-science platform. ESA Datalabs offers direct access to the data, without the need for downloading them, and augments the user experience with, among others, tutorial notebooks and team collaboration facilities. This tutorial focuses on providing hands-on training on accessing and analysing public Euclid Q1 data in the Science Archive and in ESA Datalabs. It also offers do's and don'ts for optimal workflow design, geared towards forthcoming petabyte-level data releases.
