Comparison of physical parameter estimates obtained with our default BaStA run with those obtained with Bagpipes (Kaushal et al. 2024) and Prospector (Nersesian et al. 2025).

Notes. We consider light-weighted stellar metallicities, light-weighted and mass-weighted ages, stellar masses and dust attenuations. We report the mean difference (< Δ>), the scatter (rms) as well as the mean uncertainty (< σ>) for each estimate. The statistics are based only on golden galaxies, separately for quiescent and star-forming galaxies.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
