Overview of the fit to B311. The top part shows the fits to each diagnostic. The vertical black bars indicate the normalized observed spectra, and the green line shows the best-fit model. The length of the black bars indicate the 1σ uncertainty on the data, and the shaded region shows the 1σ confidence interval of the model spectrum. The name of the diagnostic feature is given at the bottom of each panel. The bottom part shows the parameter distributions sampled by KIWI-GA. The fit parameters are displayed in the top left corner. The shade of the points is a measure of the generation: darker points are sampled in later generations. The vertical yellow line shows the best-fit value, the darker yellow shaded region shows the 1σ confidence interval, and the lighter yellow shaded region shows the 2σ confidence interval.
