APOKASC-3: evolved KIC stars with APOGEE

We used 10 independent asteroseismic analysis techniques and anchor our system on fundamental radii derived from Gaia L and spectroscopic Teff. We provide evolutionary state, asteroseismic surface gravity, mass, radius, age, and the data used to derive them for 12,418 stars.

This includes 10,036 exceptionally precise measurements, with median fractional uncertainties in {nu}_max_, {Delta}{nu}, mass, radius, and age of 0.6%, 0.6%, 3.8%, 1.8%, and 11.1%, respectively. We provide more limited data for 1624 additional stars that either have lower-quality data or are outside of our primary calibration domain. Using lower red giant branch (RGB) stars, we find a median age for the chemical thick disk of 9.14+/-0.05(ran) +/-0.9(sys) Gyr with an age dispersion of 1.1Gyr, consistent with our error model.
