KiDS acknowledgements policy

KiDS data products are openly licensed via CC BY 4.0. This means that all KiDS data products, whether directly taken from the public data releases or high-level data products from individual scientific analyses, can be freely used as long as proper acknowledgements are included in any publications or derived data products based on them. The KiDS acknowledgement policy for different types of data is specified on this page.

Scientific analyses

Many KiDS papers are accompanied by the release of high-level scientific data, such as MCMC chains, specific catalogs, or software code.

When using such data, the specific paper must always be referenced where appropriate. Furthermore, depending on the specific data set on which the analysis is based, an acknowledgement must be used. For example, for data products based on the KiDS-450 shear catalogs, the acknowledgement for that catalog (see below) is required, or for data products based on a certain public data release, the acknowledgement for that DR is required.

Catalogs

KiDS-1000 weak lensing SOM-gold catalogue

See the KiDS-1000 weak lensing SOM-gold catalogue webpage.

KiDS-450 shear catalog

Users of these data should include the following acknowledgment to the source of the data:

Based on data products from observations made with ESO Telescopes at the La Silla Paranal Observatory under programme IDs 177.A-3016, 177.A-3017 and 177.A-3018.

and should cite Hildebrandt & Viola et al. (2017), Fenech Conti et al. (2016) and accompanying papers as follows:

We use cosmic shear measurements from the Kilo-Degree Survey (Kuijken et al. 2015, Hildebrandt & Viola et al. 2017, Fenech Conti et al. 2016), hereafter referred to as KiDS. The KiDS data are processed by THELI (Erben et al. 2013) and Astro-WISE (Begeman et al. 2013, de Jong et al 2015). Shears are measured using lensfit (Miller et al. 2013), and photometric redshifts are obtained from PSF-matched photometry and calibrated using external overlapping spectroscopic surveys (see Hildebrandt et al. 2016).

Data Releases

Public data releases are accompanied by detailed release notes, which include the acknowledgements to be used, and often by data release papers. Here the acknowledgements to be used when using data from a specific DR are listed.
