Results of FORC PCA (Harrison et al. 2018) on 12 samples. a Variance explained by principal components (solid circles) is shown together with cumulative variance (blue columns). 94% of variance is explained with PC1 and PC2. b FORC for each sample is plotted on PC2 versus PC1 diagram together with end members EM1, EM2 and EM3. FORC diagrams are shown for c EM1, d EM2 and e EM3. Color scales for d and e are the same as c. Horizontal profiles on FORC diagrams along Bu = 0 are shown for f EM1, g EM2 and h EM3
