Computes the distance and age-mass-metallicity grid and prior weights on the BEAST model spectra grid

Parameters:

  • _tgrid (BEAST model spectra grid.)

  • distance_prior_model (dict) – dict including prior model name and parameters

  • age_prior_model (dict) – dict including prior model name and parameters

  • mass_prior_model (dict) – dict including prior model name and parameters

  • met_prior_model (dict) – dict including prior model name and parameters

Returns:

  • Grid and prior weight columns updated by multiplying by the

  • the distance and age-mass-metallicity weight.
