Magnitude of the radial gravitational acceleration in the plane of the disk due to our MW potential Φ (Eq. (1)), as a function of the radial cylindrical coordinate R. The solid black line represents the total gravitational acceleration. The dashed and dotted lines represent the contributions of the SMBH (dashed orange line), the bulge (dotted green line), the disk (dot-dashed blue line), and a spherical DM halo (long-dashed magenta line).
