Histograms of the median values of randomly selected Node results. These histograms display the effect on the recommended parameters caused by changing the number of Nodes that contribute to the final value (see text for full explanation). Red solid lines indicate the final recommended parameter, red dashed lines indicate the final 1σ method-to-method dispersion. The top panels show the case of HD 22879, the bottom panels the case of Tr20 781. In each boxplot, the thicker solid line indicates the median of the distribution, the box extends from the first to the third quartile, and the dashed lines extend to the extreme values.
