halomod.integrate_corr.projected_corr_gal()[source]

Projected correlation function w(r_p).

Equation taken from [1].

To integrate, we perform a substitution y = x - r_p.

Parameters

  • r (float array) – Array of scales for the 3D correlation function, in [Mpc/h]

  • xir (float array) – 3D correlation function Array of xi(r), unitless.

  • rlim (float array) – Upper limits of scales.
