Posterior distributions of the morphological properties of Rubin-GC1 modeled with ugali. Here, λ is the stellar richness, (αJ2000, δJ2000) are the centroid coordinates, ah is the angular half-light radius, ε is the ellipticity, PA is the position angle, (m − M)0 is the distance modulus, τ is the isochrone age, and Z is the isochrone metallicity.
