stam.rbf.rbfi_tracks

stam.rbf.rbfi_tracks(tracks, xparam='color', yparam='absmag', param='mass')

Compute the radial basis function interpolator instance of the stellar tracks.

Parameters:

• tracks (Table) – Stellar-track grid, as retrieved by stam.gentracks.get_isomasses, stam.gentracks.get_combined_isomasses, or stam.get_isotrack.

• xparam (str, optional) – x-axis parameter (usually the color of the stars, e.g. Gaia’s Gbp-Grp; default: “color”).

• yparam (str, optional) – y-axis parameter (usually the absolute magnitude of the stars, e.g. Gaia’s M_G; same size as x; default: “absmag”).

• param (str, optional) – The parameter to evaluate (options: “mass”, “age”, “mh”, “color”, “absmag”; default: “mass”).

Returns:

rbfi – Radial basis function interpolator instance based on the stellar tracks.

Return type:

Rbf interpolator instance
