Caption: Figure 4.
The figures containing the spectra were reformatted to display each line in individual subpanels. Mopra 3 mm spectra of the HCO+ (1–0), N2H+ (1–0), HCN (1–0), and HNC (1–0) lines. The vertical lines show the fitted velocity of the N2H+ (1–0) line in orange, if available, otherwise the velocity of the peak HCO+ (1–0) intensity in cyan.
