Values of BI center vs BII center for our sample of asteroids and for HEDs. Blue dots represent asteroids that are not members of the Vesta dynamical family, red squares represent those that are. The V symbols indicate (4) Vesta: black from Gaffey (1997) (the two points represent the maximum and minimum values over a rotational periods with the associated errors), blue from Vernazza et al. (2005). The brown circle indicates the region where the diogenite-like asteroids are located.
