In the table on the left, we list the identification numbers, cluster sizes and associated colors (to help identify clusters in figures) of the 7 identified DAR clusters. We use a yellow to red color scheme for closed DARs, and blue for partially open and wide open DARs, as described in Table 2 and depicted in Fig. 3. In the table on the right we list the four variable weightings that define the directions of our first three principal components of the PCA analysis
