Radial velocity uncertainty from Gaia vs. the Gaia G magnitude. Stars are labelled by binarity using the information from the Yoon et al. (2016) compilation, where magenta stars are binaries, black circles are non-binaries, and open grey circles represent stars of unknown binarity. The orange star is HD 135148. At fainter magnitudes, the radial velocity uncertainties in Gaia increase. The 1 km s−1 limit is marked by the grey dotted line.
