Caption: Figure 13.

Optical SFR surface densities (SFR/area; left panel) and cumulative stellar mass fraction (right panel) as a function of time in different regions of NGC 7793, from the COLIBRI solutions. The right-hand plot also shows a comparison with a constant SFH (black solid line) and a reference for an age of 1 Gyr (vertical dotted line) and for 50% of the total assembled mass (horizontal dotted line).
