The behavior of normalized AZ-distribution function vs. the normalized velocity: thick solid black curve (q = 2.5, r = 1.5, and α = 0) represents the (r, q)-distribution, dashed blue curve (q = 20, r = 0.0, and α = 0.5) agrees with Vasyliunas-Cairns distribution, dotted dashed red curve (q = 20, r = 0.0, and α = 0.2) represents Cairns distribution, dotted-dotted dashed green curve (q = 8, r = 0, and α = 0.1) shows Kappa distribution function, and dotted magenta curve (q = 30, r = 0, and α = 0) represents the Maxwellian distribution.
