Cosmic shear analysis with updated shear measurement and calibration achieved using an updated version of the lensfit code and SKiLLS multi-band image simulations.
The repository documents the analysis code used in the publication:
KiDS-1000: Cosmology with improved cosmic shear measurements (Li et al. 2023).
It contains six parts:
-
A_Prepare_Shear_Cata for preparing shear and redshift catalogues from both KiDS data and SKiLLS simulations.
-
B_Shear_Bias for calculating the mean shear biases for each tomographic bin.
-
C_Calc_2pt_Stats_Leiden for estimating the two-point shear correlation functions.
-
D_Covariance for computing the covariance matrix.
-
E_Cosmology for performing cosmological inference.
-
paper_plot for making the paper plots.
