@article{Eifler2010WeaklensingSF, title={Weak-lensing statistics from the Coyote Universe}, author={T. F. Eifler}, journal={Monthly Notices of the Royal Astronomical Society}, year={2010}, volume={418}, pages={536-544} }

Analysing future weak-lensing data sets from KIDS, Dark Energy Survey (DES), LSST, Euclid and WFIRST requires precise predictions for the weak-lensing measures. In this paper, we present a weak-lensing prediction code based on the Coyote Universe emulator. The Coyote Universe emulator predicts the (non-linear) power spectrum of density fluctuations (Pδ) to high accuracy for k∈[0.002; 3.4] h Mpc−1 within the redshift interval z∈[0; 1]; outside this regime, we extend Pδ using a modified halofit… Expand
