Correlations plots of the 11.0, 11.2, 11.207, and 11.25 µm surface brightnesses in units of W m⁻² sr⁻¹. The correlation coefficient “R” for the variables excluding (including) the points from the H II region (black), are listed in red (black). The colored star symbols represent the five template spectra from the PDR (H II region: black, atomic PDR: blue; DF 1: purple; DF 2: orange; and DF 3: pink). Only surface brightnesses with SNR > 3 from every other spaxel are considered. The data points are colored according to regions in the mosaic where those pixels are located (fifth panel): black (H II region), blue (atomic PDR), teal (west IF), purple (DF 1), yellow (region between DF 1 and DF 2), orange (DF 2), light brown (region west of DF 2), brown (region between DF 2 and DF 3), pink (DF 3) and light purple (region beyond DF 3). The contours highlighting DF 2 and DF 3 are identified through enhanced emission of H₂ 0-0 S(3) in these DFs. The red circular regions on the color-region map (fifth panel) correspond to the proplyds, as these pixels have been masked in our data analysis.
