Comparison of the SOFIA fine-structure spectra with the corresponding ¹²CO (1−0) line profiles scaled down to match either the line wings or peak strength of the [C II] (left panel) and [N II] (right panel) profiles such that the scaled CO emission is weaker than the [C II] and [N II]at all velocities. For easier comparison, we smoothed the [N II] spectra with a moving average across three spectral channels and also show the Gaussian fits to the lines. The CO scaling factors are given at each position individually.
