Galactic H I scale heights and surface density profiles predicted by our fiducial model (points with error-bars) and by a model that accounts for the extra-planar H I (from Marasco et al. 2013, solid lines). Only the averaged profiles are shown, smoothed at the spatial resolution of 0.2 kpc. The model that includes the extra-planar H I predicts slightly lower surface densities, but is roughly consistent with the fiducial case.
