get_C0

zdm.pcosmic.get_C0(z, F, zgrid, Fgrid, C0grid)[source]

Interpolate C0 from a pre-computed grid.

Performs bilinear interpolation on a pre-computed grid of C0 values to obtain C0 for arbitrary (z, F) pairs.

Parameters:

  • z (float) – Redshift at which to interpolate.

  • F (float) – Log10 of feedback parameter.

  • zgrid (ndarray) – Redshift grid points used to build C0grid.

  • Fgrid (ndarray) – Log10(F) grid points used to build C0grid.

  • C0grid (ndarray) – 2D array of pre-computed C0 values, shape (len(zgrid), len(Fgrid)).

Returns:

Interpolated C0 value.

Return type:

float
