Variation in the reduced V and H surface brightness (mag/▫″) of the bulge, disk and their sum as a function of galactocentric radius R^⋆ (″) and redshift for simulations based on SEDs corresponding to a local (13.7 Gyr old) galaxy (left) and those in an EvCon manner (right). Nebular emission has been taken into account. Contours referring to the bulge go from 22 (17) to 35 (27) mag/▫″ in V (H), and those overlaid with the disk and the total emission from 22 (19) to 28 (25) mag/▫″ in V (H) in increments of 1 mag.
