N₂H⁺(1–0) (black) and HC₅N(36–35) (gray) spectra averaged over pixels where the emission was detected above 5 σ. The red curve shows a two-component Gaussian fit to the HC₅N line profile. The blue circles indicate the peak velocity positions of each N₂H⁺(1–0) HFS component expected from the HC₅N(36–35) systemic velocity of −2.6 km s⁻¹. The vertical dashed lines mark the peaks of the two HC₅N velocity components.
