Distribution of radial velocities as a function of effective temperature for Berkeley 32 member stars. Points are color coded according to the radial-velocity error (eRV; km s−1). The solid horizontal line indicates the weighted mean cluster radial velocity, while the shaded region represents the corresponding 1σ internal velocity dispersion.
