The four spectra with the lowest p(χ2)-values of (from left- to rightmost panel) { < 0.1, 0.5,6,14 } × 10-3. The data is shown in dark-blue, and the best fit shell-model spectrum with a solid red line (the dotted red line is the intrinsic spectrum). In addition, the semi-transparent black lines show 10 randomly drawn spectra from the burned-in chains. Apart from the spectrum in the third panel which has been graded with “confidence” level 2 the other three spectra have been classified as “3”.
