Projection of the dynamical family of (179) Klytaemnestra, and of part of the family of (221) Eos, on the proper (a, sin I) plane. The members of Eos are in green, in blue if they are within 0.5 arcsec y⁻¹ from the z₁ = g − g₆ + s − s₆ = 0 secular resonance. The ones of Klytaemnestra are red points if not in the resonance, red crosses overlaid by blue points if they have |z₁ | < 0.5 arcsec y⁻¹. The dynamical family 179 is split in two parts by the resonance, which also affects 221.
