Relative probabilities of different orbital parameters (eccentricity on the y-axis, normalized pericentre distance on the x-axis). Darker pixel indicates orbital parameters that are more commonly found in the eight cosmological cluster simulations from Warnick & Knebe (2006). All haloes that were on first infall are excluded from this plot in order to make it comparable to these harassment simulations. The shaded region beneath the dashed line indicates the region of orbital parameter space where we see sufficiently strong harassment to begin stripping the stellar body of the galaxy in our harassment models (e.g. see upper-right panel of Fig. 2). Orange triangles indicate the orbital parameters for the 13 galaxies from Mastropietro et al. (2005) that have experienced at least one full orbit.
