We reproduce here part of the Euclid Quick Data Release (Q1) - Data release overview article.
Q1 is the first release of Euclid data by the SGS in a sequence ultimately gearing up towards DR3 in the early 2030s. The data processing is not yet fully mature, and many of the processing functions have identified pathways towards improvements, some that will be implemented for DR1 and some whose development will be longer and appear in subsequent data releases. We take the opportunity to remind the users of Q1 data of a few important caveats to keep in mind when working with the data.
