Specific energy (kinetic plus potential energy) relative to infall and orbital evolution of the ram pressure models. RPS-50 is shown with a blue line, RPS-100 with red, NRPS-50 with cyan, NRPS-100 with magenta. For the orbital evolution, at each snapshot we calculate the peri- and apogalacticon of the orbit of the dwarf, based on its current position and energy. The galactocentric distance of the dwarf at any given time is shown with a solid line, while the peri- and apogalacticons are shown with dashed lines.
