Fit of the stellar kinematics of the K-band spectrum integrated over an aperture r = r_e = 160   pc. The observed spectrum is shown as a thin solid line. Two different fits to the data are shown: the one obtained when using the whole stellar NIFS library (blue dashed line) and the one with the selected NIFS stellar templates (red solid line). Small spectral regions with emission or spurious lines were masked for the fit and in the plot are delimited by the vertical lines. The residuals, shifted vertically for clarity, are shown at the bottom with dots.
