Distributions of the density of stellar mass per unit comoving volume generated in the redshift bin as a function of redshift (in M_⊙ Mpc⁻³ born in the redshift bin). The dashed lines represent the cumulative distributions of the mass density generated as a function of redshift, on a linear scale ranging from 0 to 100 per cent. The dotted horizontal lines mark the 33 and 66 percentiles.
