Maps of column density (top panel), gas temperature (middle panel), and ortho-to-para ratio (bottom panel) corrected for extinction. The black contours show the H₂ 0−0 S(1) line corrected for extinction, with levels of: 4.5 × 10⁻⁵ and 1.5 × 10⁻⁴ erg cm⁻² s⁻¹ sr⁻¹). The white contours levels are 400, 420, and 500 K for T_gas and 1.2, 1.5, and 2 for the OPR. The gray boxes overlaid on the map correspond to the region where the extinction is poorly constrained.
