diameter field of view of 2dF is filled with 400 fibers. Our second observing run was with the CTIO-Hydra spectrograph. Hydra is similar to 2dF, except that it has a smaller field of view ($40\arcmin$ diameter) and $\sim130$ fibers. These observing runs are listed in Table \[table:obsrun\_spec\]. In all of these runs, PNe were also targeted. In addition to our primary aim of discovering new GCs, we tried to confirm the nature of published high-probability GCs — the brighter candidates from MAGJM96, HCH99, and Rejkuba (2001). We also observed many of the HGHH92 GCs for consistency, and in some cases to get more accurate velocities.

These data were reduced using standard packages and techniques for fiber spectroscopy. Details of the reduction are given in a companion paper on the planetary nebula system of [NGC 5128]{} (Peng, Ford, & Freeman 2004). Unlike for PNe, we do not gain in S/N by going to higher dispersion. For 2dF observations with the 1200V grating ($2.2$ Å per resolution element), we subsequently smoothed our GC spectrum by a three pixel boxcar. The resulting resolution was comparable to our setup with Hydra and did not noticeably compromise our velocity accuracy. Sky-subtraction, which is not essential
