Dynamical properties of Ton 2. Left panels: kernel density estimation (KDE) models of the characteristic orbital energy ((Emax + Emin)/2), orbital Jacobi energy (EJ), orbital pericenter and apocenter, orbital eccentricity, and maximum vertical height above the Galactic plane determined from our Galactic model (see Sect. 9) for GCs with a Galactic origin according to the classification from Massari et al. (2019). Ton 2 is shown as a black dot in each panel. Right panel: minimum and maximum value of the z-component of the angular momentum in the inertial frame, indicating the regions dominated by prograde and retrograde orbits, and those that have prograde and retrograde (P−R) or retrograde and prograde (R−P) orbits at the same time.
