Comparisons of our uncalibrated age estimates with ages from the literature. The lines and shaded bands in each panel delineate the running median and 1σ quantiles, respectively. Top left panel: age estimates from recent asteroseismic catalogues (obtained from shorter time series than the Kepler data), as indicated in the legend. Top right: open cluster ages as listed in the catalogue of Cantat-Gaudin et al. (2020). Grey dots correspond to individual cluster members (with membership probabilities > 0.95), while the red errorbars show the median statistics in each cluster with more than two members (the ones older than 4 Gyr are annotated). Bottom row: machine-learning field star estimates for APOGEE DR17 using the same training dataset as used in this paper (Miglio et al. 2021). Bottom left: DR17 astroNN ages (Leung & Bovy 2019). Bottom middle: age estimates from Ciucă et al. (2023). Bottom right: age estimates obtained by Leung et al. (2023) using a random-forest regressor trained on the APOGEE DR17 spectral latent space.
