Plots of extinction vs. declination for cut 1 and cut 2 of AG. The first cut is centered on R.A. = 4^h19^m33^s (B1950), and the second cut is centered on R.A. = 4^h18^m24^s (B1950). The gray solid line is the extinction obtained from the SFD reddening map. The dark solid line is the extinction obtained using the ISSA 60 and 100 μm images, the gray dotted line is the extinction from star counts, and the dark dotted line is the average color excess technique from AG. The average 1 σ random error for each of AG's extinction methods is shown. The peaks in extinction that are associated with named dark clouds and IRAS cores are identified. Dips in the ﹩A_{V_{\mathrm{ISSA}\,}}﹩ trace, due to artificial drops in the extinction caused by the presence of IRAS point source in the images, are also shown.
