Extrapolate the power spectra to the desired output grid.

Parameters:

  • z_ext (array_like) – Output redshifts.

  • k_ext (array_like) – Output k-vector.

  • z_in (array_like) – Input redshifts.

  • k_in (array_like) – Input k-vector.

  • power (array_like) – Power spectra to extrapolate.

  • extrapolate_option (str or float) – Extrapolation option to pass to interp1d.

Returns:

Extrapolated power spectra.

Return type:

ndarray
