IRS/SH surface brightness (10^-12 W cm^-2 sr^-1) maps of the molecular hydrogen lines (left panels, from top to bottom) H₂ S(1) at 17.0 μm and H₂ S(2) at 12.3 μm, and the H₂ S(3) line at 9.7 μm from the IRS/SL map. The right panel shows (from top to bottom) the average continuum flux density (10^-12 W cm^-2 μm^-1 sr^-1) between 14.5 μm and 15.0 μm, and the surface brightness (10^-12 W cm^-2 sr^-1) of the PAH features at 11.3 μm and 12.7 μm. The details in the maps are the same as in Fig. 5.
