NGC 4636 GC spectroscopic data. The 33′  ×  33′ DSS image shown in both panels is centred on NGC 4636, North is to the top and East is to the left. Left: location of the new fields. Note that only the inner   ×  of the FORS 2 field-of-view are shown, since the positions of the slits are confined to this area. Right: all NGC 4636 velocity-confirmed GCs. Squares show the data set from Paper I, circles the new data. The white dashed circles have radii of , and , corresponding to approximately 10, 41, and 69   kpc (at D = 17.5   Mpc), respectively.
