a–e FLI maps of the part of the 5:2 MMR with Jupiter, a ∈ 〈2.82, 2.834〉 au and e ∈ 〈0, 0.22〉. The maps were computed on a grid of 200 × 250 initial conditions and the remaining orbital elements were fixed to (i, ω, Ω, M) = (10°, 70°, 260°, 99°). The colour scale represents FLI values determined as a maximum from values obtained for six different initial deviation vectors. Stable particles are yellow, while most chaotic ones are dark blue. The maps were computed for (a) 4 kyr and (b) 10 kyr.
