Ppxf fit of the spectrum of the cluster member Gal-989. The RGB HST image of the galaxy is shown in the cut-out in the bottom-right corner of the figure. The galaxy spectrum, extracted from the dashed white circular aperture shown in the cut-out and the best-fit template are given by the black and red lines, respectively. The resulting velocity dispersion () and ⟨S/N⟩ are reported in the upper-left corner, together with the F160W magnitude of the galaxy. The green and blue points show the fit residuals. In performing the fit, we exclude the wavelengths contained in the vertical blue bands (with corresponding residuals in blue points) because of the presence of sky-line residuals.
