Orbital decomposition of FCC 177. Probability density distribution p(r, λ_z) in the left panel, age distribution p(r, t) in the central panel, and metallicity distribution p(r, Z) in the right panel of the stellar orbits in the phase space of time-averaged radius, r, vs. circularity, λ_z. The probability densities are normalized to unity within the data coverage. All the distributions are averages of multiple best-fit models that fall within the 1σ confidence level of the model hyper-parameters. The dashed line marks our orbit-based division into two components: a dynamically cold disk component (λ_z ≥ 0.8) and a dynamically hot non-disk component (λ_z < 0.8). The shadow regions are beyond the data coverage of age and metallicity maps. Similar plots for the other galaxies are shown in Figs. B.1–B.19.
