Fractional increase in capture rates due to ablation in the coplanar case, as a function of . P _{cap, ab} and P _cap represent capture rates with and without the effect of ablation, respectively. Circles, squares, and triangles show the cases with ζ = 10 ⁻⁴, 3 × 10 ⁻⁷, and 3 × 10 ⁻⁹, respectively. Dashed and dotted lines show the numerical results for the prograde and retrograde cases, respectively.
