SCEPtER-package {SCEPtER}

A grid-based estimation tool for stellar ages, masses, and radii

Description

The package estimates stellar mass, radius, and age given observational data of effective temperature, [Fe/H], and astroseismic parameters. The results are obtained adopting a maximum likelihood technique on a grid of computed stellar models.
