Abstract

Posterior distributions for the intrinsic stellar parameters (mass, age, distance, etc) and observables (e.g. apparent magnitudes) of approximately 400,000 nearby subgiant branch stars, given the measurements such as parallaxes, and given priors such as the requirement that the stars’ intrinsic stellar parameters be along a MIST stellar isochrone (Choi et al., 2016ApJ...823..102C). The 16th, 50th, and 84th percentile of the parameters with posteriors are available with the publication.
