Reduced electron and ion velocity distributions from the simulation with initial condition εo = 0.50. The blue lines represent distributions at t = 0, and the red lines represent distributions at ωpet = 480. The dotted black lines show Maxwellian velocity distributions that have been given standard deviations equal to the thermal velocity of each component distribution at ωpe t = 480. The left-hand axis labels correspond to the solid lines, and the right-hand axis labels correspond to the dashed lines.
