Fig. 2.
Oscillation of the virial ratio as a function of time for different choices of code configuration parameters for the simulation of a Plummer distribution of 105 equal-mass particles. The continuous line shows θ = 0.6, ϵ = 0.2; the dashed line represents θ = 1.0, ϵ = 0.2; the dotted line shows θ = 0.6, ϵ = 0.5; and the dash-dotted line denotes θ = 1.0, ϵ = 0.5.
