NGC 5238 clusters listed in Table 1 compared with the sample of pressure-supported stellar systems from Norris et al. (2014) in the plane opposing the logarithm of R_h and the absolute integrated V magnitude. The Norris et al. (2014) catalogue does not discriminate between GCs, UCDs, and compact ellipticals (cEs), but the distribution of the GC–UCD–cE class is dominated by UCDs and cEs for M_V ≤ −10.0 and by GCs for M_V > −10.0.
