Series of M–a FLI maps of the 5:2 MMR with Jupiter for (a) (i, ω, Ω) = (0°, 0°, 0°) and (b) (i, ω, Ω) = (30°, 180°, 60°). The eccentricity is specified in the top left corner of each map. The maps were computed for 4 kyr on a grid of 180 × 100 initial conditions, with a semi-major axis, a ∈ 〈2.805, 2.85〉 au, and mean anomaly, M ∈ 〈0°, 360°〉. The colour scale represents FLI values determined as a maximum from values obtained for six different initial deviation vectors. Stable particles are yellow, while the most chaotic ones are dark blue.
