Projected position of photometrically selected GC candidates in Hydra and Centaurus in our UI FORS1 imaging data. See text for details on the GC selection. The sources detected in the background field with the same photometric selection criteria are indicated as (blue) dots for comparison. The actual location of the background field in each cluster was about 2 degrees away, in the direction indicated by the arrow. Top: Hydra. Bottom: Centaurus. Projected physical scale is about 100 × 100 kpc per FORS pointing in Hydra, and 90 × 90 kpc in Centaurus.
