Surface mass density (Σdyn) in M⊙ pc−2 at the Solar position (Eq. (13)) along the direction perpendicular to the Galactic plane (|z| in kpc) for the north (red) and the south (blue). There are 10 000 superimposed curves per hemisphere, which arise from the same number of draws in parameter uncertainties. The shallow red and blue shapes encompass one σ standard deviation of solutions. The two solid lines in red and blue (approximately in the middle of each shape) represent median curves.
