Eccentricity of the Earth for the solutions La2010a (L10a), La2010b (L10b), La2010c (L10c), and La2010d (L10d) from  −50 to  −65 Myr. Although the various solution begin to diverge beyond 53 Ma, it is remarkable that the minima of eccentricity at 51.75 Ma, 56.25 Ma, and 58.25 Ma (in grey) correspond in all various solutions.
