Comparison of the SFH inferred with STARLIGHT for the bulge and disk of NGC 0776 (lower and upper panel, respectively). Vertical bars, color-coded according to stellar metallicity (open blue, dark blue, green, and orange for Z/10, Z/5, Z/2.5, and Z, respectively) show the contribution (in percent) of individual SSPs to the monochromatic luminosity of the continuum at 5150 Å. The sum of all SSP contributions at a given age is shown in gray. Thin vertical lines mark the (38) ages available in the SSP library we used (see BP18 for details). The labels in the upper left part of each diagram inform about the luminosity fraction of stellar populations younger than 0.1, 1, and 5 Gyr, as well as the light-weighted stellar age and metallicity. The bulge luminosity is dominated by old stellar populations, whereas more than 50% of the emission in the disk comes from stars younger than 5 Gyr.
