Correlations of the 7.7/11.2, 8.6/11.2, and 11.0/11.2 AIB surface brightness ratios, where plots involving the 7.7 and 8.6 μm AIBs measured using both the local and global continua (Fig. 1) are presented for comparison. The Spearman correlation coefficient ρ for the variables excluding (including) the points from the H ii region (black), and regions beneath the IF (teal and dark blue), are printed in red (black) in the panels. Only surface brightnesses from every other spaxel are considered in the correlation analyses. The data points are colored according to regions in the mosaic where those pixels are located (top right panel).
