Redshift distribution functions

clmm.redshift.distributions.chang2013(redshift, is_cdf=False)[source]

Chang et al (2013) unnormalized galaxy redshift distribution function, with the fiducial set of parameters.

Parameters:

  • redshift (float) -- Galaxy redshift

  • is_cdf (bool) -- If True, returns cumulative distribution function.

Return type:

The value of the distribution at z

Parameters:

  • redshift (float) -- Galaxy redshift

  • is_cdf (bool) -- If True, returns cumulative distribution function.
