Input and recovered SFHs of a series of synthetic short (10 Myr) episodes of star formation at young a), intermediate b) and old c) ages. The black, solid histogram shows the input SFH, given the adopted binning of the solution. The red histograms show the recovered SFH, as well as the fit of a Gaussian distribution as the dashed line. The mean (μ) and variance (σ) of the fitted Gaussian distribution are also listed.
