Theoretical ratios [N ii] 122 μm/[N ii] 205 μm (blue) and [C ii]/[N ii] 122 μm (red) at the temperature of 10 000 K. Blue and red areas indicate our observed ranges for [N ii] 122 μm/[N ii] 205 μm and [C ii]/[N ii] 122 μm ratios, respectively. The observed values of the [C ii]/[N ii] ratio (in red) are much higher than the theoretical value in the ionized gas for the entire map, indicating that [C ii] is mostly emitted in the PDRs and not in the ionized gas.
