Collisional family structure within the Nysa-Polana complex

The Nysa-Polana complex also contains a low-albedo family associated with (142) Polana (called “New Polana” by Walsh et al. (Walsh, K.J. et al. [2013]. Icarus 225, 283-297)), and two other low-albedo families associated with (495) Eulalia. The second Eulalia family may be a high-aP, low-eP, low-iP component of the first Eulalia family-forming collision, possibly explained by an anisotropic ejection field.
