(A): Hα radial velocity distribution around the luminosity-weighted average velocity zero-point of 95.34 km s⁻¹. HST Hα countours are overplotted in gray solid lines, with the outer most (faintest) contour tracing the 1.9  ×  10⁻⁷ erg s cm⁻² Å arcsec⁻² iso-intensity level. (B): Hα velocity dispersion, corrected only for instrumental broadening. Only spaxels with S/N ≥ 10 are shown. The gray spaxels at positions (0,14) and (8,15) are dead fibers.
