Time PDF of the hyperbolic fixed point frequency ω_hyp (first line), resonance half-width Δω (second line), and signed half-widths Δω⁻, Δω⁺ (third line), for four resonant harmonics listed in Table 2 and degree of truncation 2n from six to ten. Each time distribution results from the truncated Hamiltonian along the nominal solution spanning 5 Gyr. Kernel density estimation of the PDF is shown as a solid line, and the observed median and the [5th, 95th] percentile range are represented by a vertical dashed line and a shaded region, respectively. Frequencies are in arcsec yr⁻¹.
