Star-formation history of individual regions for different models. The vertical dotted line indicates the age of a single population. The error-bar indicates the uncertainty on the age. The red dashed curve indicates the best star-formation history found by CIGALE. The blue solid curve indicates the best star-formation history found by Le Phare. In each panel, the non-reduced χ² is given (from top to bottom: Le Phare, CIGALE, single generation). In the first two cases, the fit allows for the presence of dust, and the reddening of the best model is also given.
