Spatial distribution of globular clusters under various selections with the center of NGC 1316 as the origin. Crosses are clusters with velocities higher than the systemic velocity; open circles denote lower velocities. Large symbols are objects from the sample of Goudfrooij et al. (2001b). Upper-left panel: full sample, which is cleanly separated in an eastern and a western part. Upper-right panel: clusters with velocities between 1550 km s-1 and 1650 km s-1. There is an overwhelming dominance of clusters on the western side of NGC 1316, indicating that these clusters intrinsically have a disk-like distribution, seen almost face-on. Lower panels, from left to right: clusters in the colour interval 1.0 < CR < 1.2 (blue peak); additional selection with only clusters brighter than R = 21.5. These are bona fide younger clusters with ages around 0.8 Gyr. Almost all are located in the north-eastern bulge region; clusters in the colour interval 1.4 < CR < 1.6 (red peak); additional selection with only clusters brighter than R = 21.5. These are bona fide younger clusters with ages around 2 Gyr and appear dominantly in the bulge region.
