Description

Provides the nonlinear matter power spectrum using Halofit model Smith et al (2003) and Takahashi et al. (2012).

For PKEqual see Casarini et al. (2009) and Casarini et al. (2016).

Functions

nc_powspec_mnl_halofit_new ()

NcPowspecMNLHaloFit *
nc_powspec_mnl_halofit_new (NcPowspecML *psml,
                            gdouble zmaxnl,
                            gdouble reltol);

Creates a new NcPowspecMNLHaloFit from the transfer function tf .

Parameters

psml	a NcPowspecML
zmaxnl	maximum redshift for the halofit correction
reltol	relative tolerance (precision) for halofit computations

Returns

the newly created NcPowspecMNLHaloFit.

nc_powspec_mnl_halofit_set_kbounds_from_ml
                               (NcPowspecMNLHaloFit *pshf);

Sets mode $k$ boundaries from the linear matter power spectrum.

Parameters

pshf
