KiDS-1000 Weak Lensing data

We present the weak lensing catalogues, and associated cosmology data products from the KiDS-1000 data set, our fourth data release from the Kilo Degree Survey (KiDS-DR4).

We welcome independent analyses of the KiDS-1000 data products, provided that KiDS is acknowledged in any resulting publications. Users of these data are required to include the following statement in their paper:

Based on observations made with ESO Telescopes at the La Silla Paranal Observatory under programme IDs 177.A-3016, 177.A-3017, 177.A-3018 and 179.A-2004, and on data products produced by the KiDS consortium. The KiDS production team acknowledges support from: Deutsche Forschungsgemeinschaft, ERC, NOVA and NWO-M grants; Target; the University of Padova, and the University Federico II (Naples).

We use the gold sample of weak lensing and photometric redshift measurements from the fourth data release of the Kilo-Degree Survey (Kuijken et al. 2019, Wright et al. 2020, Hildebrandt et al. 2021, Giblin et al 2021), hereafter referred to as KiDS-1000. Cosmological parameter constraints from KiDS-1000 have been presented in Asgari et al 2021 (cosmic shear), Heymans et al 2021 (3×2pt) and Tröster et al 2021 (beyond ΛCDM), with the methodology presented in Joachimi et al 2021.
