Periodogram for the orbit of the third moon (S/2014 (130) 2). The χ² values were computed from the 2014 astrometric data only, without contributions for other moons. The osculating period P₂ was varied, while other elements were kept fixed. At the epoch T₀ = 2457021.567880 (TDB), the synthetic position was very close to the observed one. The best-fit period is 1.642 days. For comparison, the period of 0.678 days from Berdeu et al. (2022) is indicated.
