15. The Reynolds number (Re) is defined in terms of the particle's velocity and size and using the fluid kinematic shear viscosity. Δpo is chosen to ensure that Re never exceeds 0.1 (to assess the role of finite Re in LB, see, e.g. CATES M. E., DESPLAT J.-C., STANSELL P., WAGNER A., STRATFORD K., ADHIKARI R. and PAGONABARRAGA I., Proc. R. Soc. London, Ser. A, 363 (2005) 1917).

17. ∞. Hence, we cannot rule out an additional, asymptotic regime controlling the tails of the velocity distribution. We have checked this exponent both by assuming the functional form and fitting it and by analyzing the logarithmic derivative to extract the exponent (cf. BIBEN T., MARTIN P. A. and PIASECKI J., Physica A, 310 (2002) 308).
