The value of the Eulalia cluster contrast function r(C, a_c;ΔC) in the (a_c, C) space for ΔC = 1.5 × 10⁻⁵ au. Darker pixels correspond to larger r-values with a maximum of ≃7.2. Red isolines show values r = (7.1, 6.1, 5.1), and the dashed line is the correlation axis of a_c and C with close r-values. The current proper semimajor axis of (495) Eulalia is indicated by label E, and the arrows show our tested Eulalia family realizations, including the canonical choice of a_c = 2.475 au. I.e., both K. J. Walsh et al. (2013) and D. Vokrouhlický et al. (2016) argued that (495) Eulalia might have been plausibly transported to its current semimajor axis from values between ≃2.475 and ≃2.48 au via Yarkovsky drift and chaotic diffusion near the J3:1.
