Spatial (α, δ), proper motion (${\mu }_{\alpha }^{*}$, µ_δ), magnitude-parallax (G, ϖ), and color-magnitude (G_BP − G_RP, G) diagrams of the clustering result using HDBSCAN. The blue and pink points refer to the separated cluster members of NGC 2323-a and NGC 2323-b, and the gray points represent the discarded field stars. The blue and red arrows are the average proper motions of the two clusters. The corresponding fitted Gaussian profiles of α, δ, and ϖ are added in the left panels for the two clusters; the dotted lines indicate the fitted mean values.
