Fig. 21.— Ratio of velocity dispersions for NGC 6503. Black refers to scenario K, green refers to scenario KL, red refers to scenario KG and blue refers to scenario E. The thick lines use the best fit values found in Table 2 for scenario K and the best fit values for scenario KG (not published), while the thin lines correspond to the specific models identified by stars on Fig. 8. There is no thick line for scenario KL because the means for scenario KL typically fall between two separate PDFs ( § 5). 54
