Description

The Euclid satellite is an ESA mission that launched in July 2023. Euclid will observe $\sim$14,000 deg$^2$ with two instruments; the Visible Imaging Channel (VIS) and the Near IR Spectrometer and imaging Photometer (NISP). The first large data release ($\sim$1900 deg$^2$) of Euclid (DR1) is scheduled for November 2026.

The MER Processing Function within Euclid provides source catalogs containing photometric and morphological object information. Particularly, the MER pipeline performs a Sérsic fit to all Euclid data, using SourceXtractor++ (Kuemmel et al. 2022, Bertin et al. 2020) in no-detection mode. This fitting procedure was validated using Euclid data taken in the COSMOS field.

In this poster we present the results and quality assesments of the SourceXtractor++ run on Euclid sources. We highlight the final data products and the validation of the results.
