kde_nz
(*args, gals_per_arcmin2=1.0, zmax=10.0, **kwargs)[source]¶ Bases:
jax_cosmo.redshift.redshift_distribution
A redshift distribution based on a KDE estimate of the nz of a given catalog currently uses a Gaussian kernel. TODO: add more if necessary
zcat: redshift catalog weights: weight for each galaxy between 0 and 1
bw: Bandwidth for the KDE
Example: nz = kde_nz(redshift_catalog, w, bw=0.1)
