Table 2.
Properties of spectroscopically identified GCs associated with UDG3, UDG7, and UDG11. Columns list: (1) host galaxy; (2) and (3) celestial coordinates (RA, Dec); (4) line-of-sight velocity (vLOS); (5) velocity offset with respect to the systemic galaxy velocity (Δv); (6) S/N; (7) total H-band magnitude; and (8) classification as GC, intracluster GC (ICGC), or ultra-compact dwarf (UCD). Asterisks next to S/N values indicate the sources for which the local background was not subtracted. Squares next to the classification of the sources indicate whether the sources were selected as GC candidates in Iodice et al. (2020) and La Marca et al. (2022b), based on optical g and r photometry.
