The top panel shows the w_t-w₁₂ logarithmic distribution obtained for SB9 (orange) and RV-standard star (blue) subsets with Gaia DR3, RAVE DR6 measurements, and one measurement obtained directly from SB9 or the RV standard stars catalog of Soubiran et al. (2018). The bottom panel shows the w_t-w₁₂ logarithmic distribution for the same subsets shown in the top panel, but colored according to the cluster that the K-means algorithm decided they belonged to (i.e., cyan for stars in Cluster 0 and magenta for those in Cluster 1). For both panels, we added a purple line that indicates the separation between class ≤4 and class 5a-b according to our classification based on the w values.
