Mean Z and Vz over the XY plane for the RRL sample with photometric metallicity [Fe/H] > −1. In each hexagonal bin, the mean Z (left) and Vz (right) computed by a Gaussian extreme deconvolution are plotted. The RRL sample with R > 8 kpc is plotted with transparent black dots. Dashed lines indicate galactocentric rings at R = 10 kpc, 15 kpc, and 20 kpc.
