Velocity channel maps (at 1 km s-1 width) of the [C I] excitation temperature (color map in K) in M17 SW, estimated from the R = I([C I] 369 μm)/I([C I] 609 μm) line intensity ratio, and assuming LTE conditions and optically thin emission. Only velocity channels and pixels with emission larger than 3σ in both [C I] lines are shown.
