Notes. We note that the S/N is calculated around the Mgb for the XSH spectra, in a bluer region in S20 and over a larger wavelength window ([4500–6500] Å) for the GAMA spectrum of KiDS J0847+0112. The velocity dispersion of the GAMA spectrum is computed using PPXF in the same configuration used for the XSH spectra. The uncertainties on the XSH velocity and velocity dispersion values are computed as standard deviation of the distributions shown in Fig. 5, whereas the central values are obtained with the best configuration.
