Scaling relations for globular cluster systems in early-type galaxies.
  II. Is there an environmental dependence?
  The current properties of globular cluster systems (GCSs) are the result of
the evolution experienced by their host galaxies, which shape the richness of
the GCS as well as its spatial distribution, among other features. We carry out
an analysis of the projected radial distribution of globular clusters for a
sample of almost 30 early-type galaxies (ETGs) of intermediate and low
luminosity, located in cluster environments (Virgo, Fornax and Coma). We also
include in the study six ETGs, for which the parameters of their GCS radial
profiles are publicly available. The final analysis is performed on an enlarged
sample (~ 100 GCSs), by adding the GCSs of ETGs from our previous paper (Paper
I). Scaling relations involving different parameters of the GCSs are obtained
for the whole sample and complement those obtained in Paper I. Several of such
relations point to a second-order dependence on the environmental density.
Finally, the results are analysed in the literature context.
