Notes. Left to right: total initial mass MT = MD + MB (in units of 1012 M⊙), corresponding (initial) gas mass Mg [in units of 1012 M⊙], redshift zi at which the proto-halo is selected from the background in the cosmological grid, mean halo over-densities (⟨ρ⟩−ρb)/ρb = [δρ − 1]i (ρb is the background density) at the redshift zi, initial proper physical radius of the halo [in kpc], redshift of the last computed model zf, corresponding age tf [in Gyr], virial radius of the whole system Rvir [in kiloparsecs], half-mass radius R1/2 at zf, and the total stellar mass Ms at the final redshift [in units of 1012 M⊙].
