gen_spectral_grid_from_stellib_given_points

beast.physicsmodel.creategrid.gen_spectral_grid_from_stellib_given_points(osl, pts, bounds={'dlogT': 0.1, 'dlogg': 0.3}, chunksize=0)[source]
Generator that reinterpolates a given stellar spectral library on to

an Isochrone grid

It will iterate over a list of pts points and generate

chunksize models until all the list of points is processed

Parameters:

  • osl (stellib.stellib) – a stellar library

  • pts (dict like structure of points) – dictionary like or named data structure of points to interpolate at must contain logg, logT, logL, and Z

  • bounds (dict, optional (default={dlogT:0.1, dlogg:0.3})) – sensitivity to extrapolation (see grid.get_stellib_boundaries)

  • chunksize (int, optional (default=0)) – number of models to generate at each cycle. If default <= 0, all models will be returned at once.

Returns:

g – Spectral grid (in memory) containing the requested list of stars and associated spectra

Return type:

SpectralGrid
