Mean radial velocity to radial velocity dispersion ratio as a function of cluster age for different age estimates (from left to right): Kharchenko et al. (2013), Bossini et al. (2019), Dias et al. (2021), and Hunt & Reffert (2023). Errors on the y-axis are obtained from the MCMC sampling of the posterior, while those on the x-axis (if present) are age errors provided by the different catalogs. The zero-level expansion is marked by the dark dashed line.
