Distribution of velocity differences for stars in common between our dataset and that of Kirby et al. (2014). A normal distribution with mean and standard deviation N( μ, σ)∼(0, 1) is overplotted for direct comparison (continuous line), together with a normal distribution N( μ, σ) ∼ (0.9, 1.3) (dot-dashed line) fitted to the velocity differences after discarding the most deviant measurement.
