Analysis for HD 35114 with two equal-mass planets on eccentric orbits. On the axes, the eccentricity of the inner (e₁ ) and outer (e₂) planets. The graduation of colors represents values of M_p∕M_J. The black line represents the approximate detection limits: points above the line are undetectable whereas points below are detectable. The discontinuity at e = 0.3 is due to the passage from Wisdom’s equation to Mustill and Wyatt’s one.
