Left panel: Toomre diagram of the kinematically separated literature samples and the Gaia 1 stars. As in the previous figures, light gray points are thin disk stars, dark gray ones are for the thick disk, and black symbols denote stars on halo-like orbits. The right panel uses OCs from the compilation of Vande Putte et al. (2010) as a comparison sample, color-coded following the decomposition procedure of Bensby et al. (2014).
