Left panel: Hα radial velocity as a function of the radial velocity in lines tracing low-ionization ([N II], [S II]) and high-ionization gas (He I, [Ar III]). The points are color-coded by S/N. The 1:1 Hα velocity line (solid gray), with ±5 (dashed) and ±10 km s⁻¹ (dotted) lines, are plotted for orientation. Only spaxels with S/N ≥ 15 or within the overplotted contours in the right panel are shown. Right panel: spatial distribution of the spaxels, color-coded by S/N.
