Comparison between the extinction map constructed in this work and the Spitzer/IRAC 8 μm emission distribution. Left panel: Spitzer/IRAC 8 μm map at 12″ resolution, with cyan contours showing the mean A_V derived in this work. Right panel: pixel-by-pixel comparison, shown as a density plot of A_V versus ﹩{\rm{log}}({I}_{8.0}﹩), with colors from red to blue indicating high to low point density.
