Notes. DM halo profile: (1) type, ISO = isothermal, NFW = Navarro–Frenk–White; (2) concentration or central density; and (3) V200 or core radius. Stellar disc: (4) central surface density Σ⋆, 0 = ρ⋆, 0/(2R⋆); (5) scale radius; and (6) scale height. Bulge (as exponential sphere): (7) central density and (8) scale radius.
