Dark Energy Survey Year 6 Results : Photometric Dataset for Cosmology

Puntos clave

The DES Y6 Gold dataset includes nearly 5000 deg2 of imaging data collected over six years.
669 million objects are classified, achieving a photometric depth of iAB ∼ 23.4 mag with a signal-to-noise ratio of ∼ 10.
This curated dataset provides improved measurements and object classification, essential for cosmological analyses.
The high-quality photometric calibration ensures a uniformity across the observed sky, which is crucial for reliable cosmological studies.

Resumen

We describe the photometric dataset assembled from the full 6 yr of observations by the Dark Energy Survey (DES) in support of static-sky cosmology analyses. DES Y6 Gold is a curated dataset derived from DES Data Release 2 (DR2) that incorporates improved measurement, photometric calibration, object classification and value-added information. Y6 Gold comprises nearly 5000 deg2 of grizY imaging in the south Galactic cap and includes 669 million objects with a depth of iAB ∼ 23.4 mag at a signal-to-noise ratio ∼ 10 for extended objects and a top-of-the-atmosphere photometric uniformity
