Intrinsic (i.e., deconvolved) parallax (top panel), and PM (bottom panel) distributions for the eight clusters in the region defined by the preliminary Galactic coordinates ranges. The cluster names are reported in the top left panel. The black lines show the parallax and PM ranges adopted for selecting Gaia sources. The top right panel shows a narrower parallax range centered around the W345 star clusters to visualize the cluster parallax distributions better. Finally, in the bottom panel, the different contours represent the 1σ (dotted lines), 2σ (dashed lines), and 3σ (solid lines) regions for each cluster. The correlations among μ_α, and μ_δ are also visible.
