Top: H magnitude distributions of Spitzer detected asteroids: the solid line corresponds to the Zellner et al. (1975) Main Belt Asteroid (MBA) I region (2.06 <a ≤ 2.5), the dotted line corresponds to MBAII (2.5 <a ≤ 2.82), the dashed line corresponds to MBAIII (2.82 <a ≤ 3.27). Bottom: diameter distributions of the Spitzer detected asteroids in the same regions.
