hmf.alternatives.wdm.MassFunctionWDM.n_eff

property MassFunctionWDM.n_eff

Effective spectral index at scale of halo radius, len=len(m)

Notes

This function, and any derived quantities, can show small non-physical ‘wiggles’ at the 0.1% level, if too coarse a grid in ln(k) is used. If applications are sensitive at this level, please use a very fine k-space grid.

Uses eq. 42 in Lukic et. al 2007.
