Fig. 1


Photometric and structural parameter distributions for the simulations. Density clouds represent the parameter distributions of the 10 000 3D simulations of realistic bulge + flared disc light distributions created from the observations as a function of the morphological type, T. Dots represent the observations from Graham (2001), Kregel et al. (2002), Bizyaev et al. (2014) and Mosenkov et al. (2015). Upper row, from left to right: disc absolute magnitude Mabs,disc, disc central surface brightness μ0, disc scale length hR, bulge-to-disc ratio B/D, and disc radial-to-vertical scale-lengths ratio hR/hz. Lower row, from left to right: bulge absolute magnitude Mabs,bulge, bulge surface brightness at the bulge effective radius μe, effective radius re, bulge Sérsic index n, and the radial gradient of hz, Rhz. The green diamond represents the MW.
