Euclid’s Ground Segment Implementation Review is an official ESA’s review of the status of the Ground Segment of the project, including the SGS (Science Ground Segment) to which PIC belongs. 

PIC contributed to the data package for the Data Processing Panel, which shall assess the status of the Processing Functions (PF) as well as the ability of the SGS to produce and distribute Q1 data products. In order to demonstrate this, the SGS simulated and processed the equivalent to a full day of observation (~10 square degrees). PIC played a key role in this effort, providing the input catalogs, running part of the simulations and producing the documentation relative to the Simulations PF.

The GSIR production (SWF1 & 2 & 3) laid the groundwork for the much more ambitious Scientific Challenge 8 Main Area production, taking place in mid 2021, which will cover ~600 square degrees. Image by H. Aussel.

The object catalog of the Data Release 2 (DR2) of the Dark Energy Survey (DES) has been ingested into the CosmoHub service. DES is based on optical/near-infrared imaging by the Dark Energy Camera mounted on the 4-m Blanco telescope at Cerro Tololo Inter-American Observatory in Chile. DR2 consists of single-epoch and coadded images, a source catalog derived from coadded images and associated data products assembled from 6 years of DES science operation. The release includes data from the 5000 deg2 wide-area survey covering the southern Galactic cap in 5 broad photometric bands.

The now available catalog consists of 691,483,608 objects with about 480 parameters. The total size of the catalog is ~3 TiB. The DES DR2 catalog is available for exploration and download at cosmohub.pic.es.
