Figure 13.

Principal component analyses of the FHR5 best-fit models from Search 2. The 55 best-fit models (Table 3) were grouped by principal component analysis into five groups, of which three groups were predominant in terms of the number of 48 models they contained. These are shown as PC1, PC2, and PC3 (black, 19 models; red, 16 models; green, 13 models) and exemplified by the first three principal components (PC2 versus PC1 and PC3 versus PC2).
