Spectrum of the cluster galaxy 80726 in M0416, extracted from a circular aperture with radius r = 0.5″ centered on the galaxy luminosity center. The black line shows the measured spectrum, while the red line shows the fit spectrum, obtained with the pPXF pipeline, from rest-frame 3700–5100 Å. On the bottom, the residuals between the two spectra are shown as green dots. The gray bands highlight masked regions. On the top, the values of the extracted kinematic parameters are listed: the velocity dispersion, σ, and the peculiar velocity, v, in kilometers per second, with their corresponding uncertainties, and the average signal-to-noise ratio ⟨S/N⟩.
