The G-YOC sample from the merging of the Cantat-Gaudin et al. (2020) and Tarricq et al. (2021) catalogs, in Galactic Cartesian coordinates. The selection criteria are ∣r∣ ≤ 3.5 kpc and ﹩\mathrm{log}(\mathrm{Age})\leqslant 7.5﹩, resulting in 309 YOCs (left), of which 183 have their vertical velocity component measured (right). The color codes for Z (pc) and V Z (km s−1) are shown at the top. The X- and Y-axes take positive values toward the Galactic center and the Galactic rotation directions, respectively. The Sun is at (0, 0). The shown spiral arms are, from left to right: Perseus, LA, and Sagittarius. The spiral-arm parameters are taken from Castro-Ginard et al. (2021), with the width of the fixed arms based on Reid et al. (2014).
