Weak-lensing statistics from the Coyote Universe

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 (P ) to high accuracy for k [0.002; 3.4] h Mpc -1 within the redshift interval z [0; 1]; outside this regime, we extend P using a modified HALOFIT code.
