资源简介:

This repository contains: a) 100 samples of mass maps created from the Dark Energy Survey (DES) Year 3 (Y3) weak lensing data using the Kappa Reconstruction for Mass Mapping (KaRMMa) algorithm (desy3_karmma_maps.zip), b) The DES-Y3 data used for running KaRMMa (karmma_data.zip). KaRMMa is a Bayesian forward modelled mass mapping algorithm that produces mass map samples assuming a lognormal prior on the convergence field. - desy3_karmma_maps.zip: The files contain the masked HEALPIX maps as a numpy array. The repository contains the associated HEALPIX mask and a script to produce the HEALPIX maps from the masked array. - karmma_data.zip: Contains the pixelized shear maps, associated C(l)'s, redshift distributions, and the mask files used in the KaRMMa run on DES-Y3 data.
