Scale-height modulation factor λ_H obtained by solving Equation (30) (λ_H,OL, left) and from the simulations (﹩{\lambda }_{H,{\rm{sim}}}﹩, right) for ﹩{\dot{M}}_{{\rm{in}}}=1{0}^{-7}\,{M}_{\odot }\,{{\rm{yr}}}^{-1}﹩ (top) and 10⁻⁶ M_⊙ yr⁻¹ (bottom) at t = 28 kyr. The simulated scale-height variations agree well with those predicted by the analytic framework of G. I. Ogilvie & E. M. Lynch (2019).
