Notes. Semimajor axis a, perihelion distance q, inclination i, eccentricity e, color taxonomy, spectral slope, and the average absolute visual magnitudes (V or R-band) of 19 TNOs ordered according to increasing inclination. For H_V used in our analysis, see Table 5. The horizontal line marks the limit of dynamically cold and hot classicals according to our dynamical analysis using the Gladman system. * Denotes a known binary system (Noll et al. 2008).
