Measured particle scale height, H_p, in units of the gas scale height, H, as a function of the particle Stokes number for the simulations of the turbulent VSI, and the laminar disc plus stochasistic kicks at R = 1.8r_p, averaged between 150 and 200 orbital periods. Shown are the results of the runs used in this paper (labelled with blue and green crosses), and of Stoll & Kley (2016) and Fromang & Nelson (2009) indicated with light blue and black circles, respectively. Additionally, we overplot the fit of the VSI particle scale heights by Youdin & Lithwick (2007; see Eq. (26)).
