Distribution of v_ℓ and ${\sigma }_{v_{\ell }}$ vs. X coordinate. The top panel shows how v_ℓ changes with different distances from the Sun for two metallicity bins, metal-rich (denoted with red points) and metal-poor (represented by blue squares). The dashed black line represents results from Sanders et al. (2019) for RC stars. The bottom panel presents a dispersion profile of v_ℓ over the same distance range with the same two metallicity samples. The black line again represents the results from Sanders et al. (2019) for the dispersion of RC giants. The gray and green markers denote the same metallicity bins (metal-rich and metal-poor) but for transverse velocities, dispersions, and X-coordinates estimated using distance based on visual passbands, showing that the transverse velocities do not significantly depend on the extinction map used. Similar to Fig. 13, all stars were selected within |ℓ| < 2 deg.
