We used FLAMES on the VLT to obtain accurate velocities for 149 GCs, within a ∼500x150kpc strip centered on NGC 1399, the Fornax central galaxy. These objects are at the very bright tail (MV≲-9.5) of the GC luminosity function, overlapping the so-called "ultra-compact dwarfs" magnitude range. Eight of the brightest FLAMES-confirmed members indeed show hints of resolution in the subarcsecond pre-imaging data we used for selecting the ∼500 targets for FLAMES spectroscopy. Description: The spectroscopic follow-up was done using the GIRAFFE/MEDUSA mode of FLAMES, the multi-object fibre-fed spectrograph on the UT2 of the VLT. File Summary:

Note (1): In table 3, names as fccNNNN are identified as FCC NNN in Simbad, and newly detected dwarves, newdwN, are identified as [BAL2007] newdwN. Note (2): Classes as follows: A = very secure velocity estimate, where 98% or more of the ELODIE templates, as well as more than half of the simultaneous templates, agree within the velocity errors. B = 60%-97% ELODIE agreement but less than half of the simultaneous templates give consistent velocities C = less than 60% agreement between ELODIE templates; these possible members would require a definitive, independent confirmation. Note (3): * table1 (globular clusters): The comments include a comparison with GCs observed in previous studies: Mieske et al. (2004, Cat. J/A+A/418/445, prefix "fcos"), and Dirsch et al. (2004, Cat. J/AJ/127/2114, prefix "dir"). Among the brightest objects, gc302.3, gc46.30, gc241.1, gc85.30 and gc271.5 show marginal signs of resolution, with FWHM about 10% larger than the seeing. Higher resolution data would be needed to classify them as likely new UCDs. * table2 (ultracompact objects): The comments include a comparison with objects observed in previous studies: Phillipps et al. (2001ApJ...560..201P, prefix "2dF"), Mieske et al. (2004, Cat. J/A+A/418/445, prefix "fcos''), Dirsch et al. (2004, Cat. J/AJ/127/2114, prefix "dir''). * table3 (dwarves): The comments include a comparison with velocities available in the literature, when available.
