Distribution of total density n = ni + ne, J/ec, charge, and electron density ne for B0/δB0 = 1. The charge is fit by a lognormal (shown over the fitting interval). The total density and electron density are subtracted by their mean value, and the absolute values of ρ/e and J/ec are used. Each quantity has units of density and is normalized by the mean electron density. The visual structure of the density and charge are illustrated in the inset over a small portion of the simulation region. The current is less strongly coupled to the density than in the case of B0/δB0 = 10, and large fluctuations deviate somewhat from a lognormal form.
