V-shaped formation of the asteroid family Themis, and the positions (outside of the V) of asteroids (223) Rosa and (268) Adorea, currently considered Themis family members. Even if the smallest diameter is adopted for Rosa, the asteroid cannot be placed within the Themis V shape. The Themis family is truncated at a_p = 3.24 au, due to the presence of the nearby 2:1 mean motion resonance. The V shape is detected according to the procedure described in Appendix C.
