hmf.mass_function.hmf.MassFunction.n_eff¶
- property MassFunction.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.
