Notes. The parameters displayed in the table are determined with a simple simplex algorithm (e.g., Press et al. 1992) on some trustable dynamical ranges accounting for force softening and a halo extension inferred via visual inspection. Given the rough nature of the measurements due to the limited force resolution of the simulations, no error bars are provided, so the values of the parameters are only indicative. For the three sine waves case the fit is performed using the ϵ = (3/4, 1/2) highest resolution PM simulation, namely PM-ANI2-UHR.
