Two-particle dispersion in anisotropic MHD turbulence

This is ASCII data for Figure 3 from Pratt, Busse, Mueller 2020 "Lagrangian Statistics for Dispersion in Magnetohydrodynamic Turbulence". The time values are provided with Figure 1. The figure shows the evolution of the mean-square relative dispersion in homogeneous isotropic Navier-Stokes turbulence (simulation HNOVIS), homogeneous isotropic MHD turbulence (simulation ANOVIS0), and homogeneous anisotropic MHD turbulence (simulation ANOVIS3). The behavior for pairs with an initial separation of 2 eta_kol is shown (a) for particles initially separated in the direction perpendicular to the mean magnetic field and separation distance perpendicular to the field measured, and (b) for particles initially separated in the direction parallel to the mean magnetic field, separation distance aligned with the mean magnetic field is measured.
