Functions

color_interpolation(logg_val, logteff_val, ...)

Trilinear interpolation of a single color grid over stellar parameters.
fastar.interpolate.color.color_interpolation(logg_val, logteff_val, fmet_val, ulogg, uteff_log10, ufmet, grid)[source]#

Trilinear interpolation of a single color grid over stellar parameters.

These stellar parameters are (logg, log10(Teff), [Fe/H]).

Parameters:

  • logg_val (float) – Target surface gravity (logg).

  • logteff_val (float) – Target effective temperature (log10 Teff).

  • fmet_val (float) – Target [Fe/H].

  • ulogg (array-like) – 1D grid points along each axis.

  • uteff_log10 (array-like) – 1D grid points along each axis.

  • ufmet (array-like) – 1D grid points along each axis.

  • grid (array-like, shape (len(ulogg), len(uteff_log10), len(ufmet))) – The color grid to interpolate.

Returns:

Interpolated color value.

Return type:

float
