Dependence of the absolute magnitude H on the proper semi-major axis a_p for the eight families: Flora, Koronis, Eos, Eunomia, Phocaea, Themis, Maria and Alauda with the likely positions of the family centers (vertical lines). We also plot the possible range of the (a_p, H) borders (two thick lines) of each family for values of the parameter C from Brož et al. (2013) (different values correspond to a different initial extent of the family or different age and magnitude of the Yarkovsky semi-major axis drift.). The pink triangles represent the members from our sample (M), green circles borderline cases (B) and blue circles interlopers (I). Borderline cases and interlopers are identified by several methods including the position in the (a_p, H) diagram, and thus could also lie close to the center of the family (e.g., in the case of the Flora family).
