Two-dimensional distribution of GC candidates in six C − R color intervals. North is up, east to the left. The origin is NGC 1316. See text for details. The most important observations are: there are clusters bluer than C − R = 1.1, clusters in the range 1.1–1.3 show a symmetry with a shifted major axis, clusters of intermediate color define mostly the bulge, but there is also an overdensity of clusters related to outer morphological features to the south.
