MMGAN Model and Samples

This dataset is for the results of Generative modelling for mass-mapping with fast uncertainty quantification (Whitney et al. 2024).

We include the weights of the trained MMGAN model used within the paper, as well as our main result: The COSMOS field convergence map reconstruction made with MMGAN. For this we include the MMGAN convergence map reconstruction, the associated uncertainty map, as well as the approximate posterior samples used to build the final reconstruction.

We also include 3 pseudo-COSMOS-style mock maps, made using the kappaTNG mock weak lensing suite and (Schrabback et al. 2010) COSMOS shape catalogue.
