Parametrized cosmological mass maps dataset

<strong>Parametrized cosmological mass maps dataset</strong> This dataset consists of the non-tomographic training and testing set without noise and intrinsic alignments. It was introduced in the following paper<br> Fluri, Janis, et al. "Cosmological constraints with deep learning from KiDS-450 weak lensing maps." Physical Review D 100.6 (2019): 063514.<br> Furthermore, this dataset is released with the following paper:<br> Perraudin, Nathanaël, et al. "Emulation of cosmological mass maps with conditional generative adversarial networks." arXiv preprint arXiv:2004.08139 (2020).
