Notes. Column 1 reports the name of the UDG candidate. Columns 2 and 3 give the total number of GC candidates inside R = 1.5 Re and 5 Re, respectively. Columns 4 and 5 report the halo mass and the V-band halo mass-to-light ratio, respectively. Column 6 lists the GC specific frequency derived from the total number of GCs inside 5 Re. Column 7 provides some details on the presence of nuclear star clusters (NSC); if present, the g magnitude and the projected galactocentric distance from the galaxy core, Rproj, are reported.
