Notes. In Cols. 1 and 2 we report the kind of fit we performed or source we used and the wavelength range used to derive the stellar kinematics, age, and metallicity, respectively. Columns 3 and 4 list the systemic velocity and velocity dispersion derived for UDG11 inside 1Re (see Sect. 5.1). In Cols. 5 and 6 we report the estimates of the metallicity and age derived for UDG11 inside 1Re (see Sect. 5.4), and for GC1.
