Confusion matrix comparing the dynamical and chemical classifications for stars possessing both metallicity and α-abundance estimates from APOGEE or GALAH. Each tile presents the total number of stars (top), precision (middle, fraction normalised along columns), and recall (bottom, fraction normalised along rows). For instance, 3242 stars are consistently classified as belonging to the thick disk by both methods. This corresponds to 68.15% of targets that were kinematically classified as thick disk stars, and 58.79% of targets that were chemically classified as such.
