Robustness of the best fit for the F0 (top-left), YVSG (top-right), YPAH (bottom-left), and YBG (bottom-right). We use the best fit SED given by the minimisation method (YBestFit) and create a new SED choosing a random flux value in each band from a Gaussian distribution having the best fit flux as a mean value and the observational uncertainty as σ. The best fit parameters of the new fit (YNew) are then compared with those obtained initially from the minimisation method.
