Description

Provides a linear matter power spectrum as a function of mode $k$ at a redshift $z_0$ computing a spline, whose knots and the respective $P(k, z = z_0)$ values are provided in a file. The time evolution of the power spectrum is computed using the growth function.

Functions

nc_powspec_ml_spline_new ()

NcPowspecMLSpline *
nc_powspec_ml_spline_new (NcmSpline *Pk);

Creates a new NcPowspecMLSpline from a spline Pk of the power spectrum, $P(k, z=z_0)$ at a given redshift $z_0$.

Parameters

a NcmSpline

Returns

the newly created NcPowspecMLSpline.

nc_powspec_ml_spline_set_spline (NcPowspecMLSpline *ps_fs,
                                 NcmSpline *Pk);

Attributes a spline of the power spectrum at a redshift $z_0$, P(k, z_0), from Pk .

Parameters

ps_fs	a NcPowspecMLSpline
Pk	a NcmSpline

nc_powspec_ml_spline_peek_spline ()

NcmSpline *
nc_powspec_ml_spline_peek_spline (NcPowspecMLSpline *ps_fs);

Parameters

ps_fs

a NcPowspecMLSpline

Returns

the spline of the power spectrum at a redshift $z_0$, P(k, z_0).
