Notes. NID (Nidever et al. 2002), CHU (Chubak et al. 2012), WOR (Worley et al. 2012), FAM (Famaey et al. 2005), MER (Mermilliod et al. 2008, 2009), NOR (Nordström et al. 2004), and RAV (RAVE DR5 Kunder et al. 2017). Median and median absolute deviation (MAD) are relative to the RV difference of our catalogue minus the other ones. N* and No refer to the number of stars in common and the number of outliers with RV differences larger than 3 km s−1.
