PPXF fits for the GC sample. GIRAFFE spectra are shown in black, the optimal model template in orange, and residuals of the fit are shown underneath in purple. The greyed-out areas are regions of strong sky residuals which are masked out in the fitting procedure. Radial velocities and velocity dispersions are shown for each corresponding GC. Velocity dispersion values less than ∼4 km/s are below the resolution limit of our analysis and therefore unreliable.
