The posterior distributions of Leo VI’s morphological and isochrone properties modeled using ugali. We simultaneously fit the system’s stellar richness (λ), centroid coordinates (αJ2000, δJ2000), angular semimajor axis length (ah), ellipticity (ϵ), PA of the major axis, distance modulus ((m − M)0), age (τ), and metallicity (Zphot).
