Description: This study determined fundamental astrophysical parameters—age, metallicity, distance, and reddening—for 5,056 open star clusters using Bayesian Nested Sampling and PARSEC isochrones fitted to Gaia DR3 data. The method uses a uniform pipeline to derive photometric [Fe/H] for all clusters without external abundance models. This creates a consistent reference baseline for Galactic science.
