N₂H⁺ (3–2) data for a sample region in the north of G0.253+0.016. Panel a) presents channel maps. The velocity in km s^-1 is indicated in the upper left corner. Panels b) and c) show spectra extracted towards selected positions. Black lines in these plots depict multi-component Gaussian fits to selected velocity ranges of the spectra, where gray lines trace the structure of the widest component. For each component we indicate the full width at half maximum, Δv.
