Globular clusters in galaxies beyond the Local Group. IV. The elliptical galaxies NGC 524 and 1052.

The global properties (total populations and spatial structures, derived by starcounts) of the globular cluster systems in two large E/S0 galaxies are described: NGC 524, the central giant in the compact cluster CfA 13 with V(0) of about 2300 km/s; and NGC 1052, the only major elliptical in the loose southern group HG 44 = Cetus I V(0) of about 1150 km/s. In NGC 1052, the halo cluster system is small (specific frequency S of about 3, on the low end of the range for ellipticals) and more compact than normal (surface density sigma of about r to the -2/3 power). The globular cluster system in NGC 524 is somewhat more populous (S of about 6, similar to the Virgo ellipticals) and structurally more extended (sigma of about r to the -1.7 power). It is concluded from NGC 524 that privileged location of central dominance within a cluster does not seem to be enough by itself to guarantee the existence of an anomalously populous cluster system (S of about 20) such as is seen in the central supergiant ellipticals in Virgo, Fornax, and Hydra.
