Stellar mass estimations. Left: Spectral energy distribution (SED) for galaxy ID = 22 055 at z = 0.9856 from field J1039p0714. The black line represents the best fit template. The solid bars represent the pseudo-narrow bands. Right: Stellar-mass vs redshift for the galaxies in the DR2 catalogue at 0.35 < z < 1.5. The squares represent the galaxies within 500 km s⁻¹ of the Mg II absorbers and with impact parameters b < 100 kpc. The histogram shows the normalised stellar mass distributions.
