Individual kinematic fits for the first 18 out of the 32 Voronoi-binned spectra. The best-fit gas lines are subtracted for better visualization of the Ca II triplet features (marked with orange lines). The blue-shaded region marks where we boosted the noise levels around the Hα and N II lines. The gray bars represent the observed data, with the width marking the bin width and the height marking the original 1σ noise level. The vertical gray lines represent the boosted 1σ noise level. These 1σ noise levels for each bin are estimated from random sampling given the covariance matrix. The measured velocity dispersion σ_los is also annotated in each panel.
