The OCCAM DR19 sample based on T. Cantat-Gaudin et al. (2020) membership plotted in the Galactic plane, color coded by [Fe/H]. Diamond points are clusters that were in the OCCAM DR17 sample, and triangle points are clusters that are new in the DR19 sample. The concentric circles show RGC = 5, 8.34 (the solar radius), 12, and 17 kpc.
