The Weak Lensing Peak Statistics in the Mocks by the inverse-Gaussianization Method

1 code implementation29 Jan 2020 Zhao Chen, Yu Yu, Xiangkun Liu, Zuhui Fan

We apply the inverse-Gaussianization method proposed in \citealt{arXiv:1607. 05007} to fast produce weak lensing convergence maps and investigate the peak statistics, including the peak height counts and peak steepness counts, in these mocks.
