Total intensities of all considered species for the regions described in Table 3, normalised by the respective total CO intensity. Due to the noise level of the region and its total CO intensity, a normalised total intensity of 0.1% is not detectable for region (c). Therefore, a green line approximating the detection limit for a 5σ feature (assuming the median line width of the region and σmedian) is added in this case. Detections below that limit indicate that the local noise is below σmedian. Error bars refer to the fit uncertainties.
