Notes. Column 1: GC number as marked in Fig. 3. Columns 2 and 3: coordinate of the sources. Column 4: estimated line-of-sight velocity and uncertainty. Column 5: difference between the estimated radial velocity of the sources and the radial velocity of the UDG11. We adopted as radial velocity for the UDG11 the value reported in Sect. 5. Column 6: magnitude in the r-band from the VST photometry. Column 7: S/N per pixel of the background-subtracted spectrum. Column 8: distance of the sources in terms of the effective radius of the UDG. Column 9: source classification.
