Notes. (a)Denotes that potentially the ultra-diffuse galaxy is embedded in multiple strong external fields, in which case we present the smallest velocity dispersion value from all of them. (b)The values here are slightly higher than in Famaey et al. (2018) because of very slightly different assumptions for the baryonic mass of the UDG and host, as well as in the definition of the upper limit. (c)NGC 3625-DGSAT-2 could also be associated to NGC 3619 (second shown entry) instead of NGC 3625 (first shown entry), which is closer to us, therefore we provide the predictions for both cases.
