Notes. The main parameters that might affect the shape of the recovered SFH are the smoothing parameters ( μx and μZ) and the extraction mask (extraction A or B). With these runs we cover all reasonable values of smoothness in the solution. We also show the rms, computed as the mean values of the absolute differences between the data and the fit, as a proxy for the quality of each fit.
