Notes. Column 1 indicates the instrument/grism combination. Column 2 indicates the radial range in which the spatial binning has been done, with respect to the position of the nucleus the long slit crosses. Column 3 is the position angle of the slit, measured East from North (see Fig. 1 for the exact slit positioning). Column 4 indicates the signal-to-noise ratio of each spectra at the central wavelength of the range used for the pPXF fit. Column 5 is the velocity difference with the system velocity of the cluster. Column 6 indicates the velocity dispersion and its error.
