Probability density and metallicity profiles. Panel a-1: probability density of dynamically hot orbits with λ_z <  0.5 (red) and warm orbits with 0.5 <  λ_z <  0.8 (orange) as a function of radius for NGC 1380. The red and orange thick and dashed curves are the mean and 1σ scatter of our best fitting models. The vertical line at r = 3.5 kpc marks the separation of the bulge from the hot inner stellar halo. Panel b-1: metallicity distribution of hot and warm orbits as a function of radius for NGC 1380. Panels a-2 and b-2: same but for NGC 1427.
