Measured LOS velocity dispersion profile of galaxy 80726 as a function of the radial distance from the center, in both arcseconds (bottom) and kiloparsecs (top). The red lines along the horizontal axis show the uncertainty on the measurement position due to each annulus width, as shown in Fig. 2, while the ones along the vertical axis represent the uncertainty on each measured σ_LOS, obtained from the pPXF pipeline.
