Sky coordinates of all extracted sources that fulfill the morphology criteria. The most transparent sources fulfill only the morphology criteria (Sect. 3.3.1). The sources with medium transparency additionally fulfill the velocity criteria (Sect. 3.3.2). Finally, the sources with black contours are those that fulfill all previous criteria and have no emission lines, and are therefore the final GC candidates. The colors of the fields are the same as in Fig. 7, and the center of NGC 3311 is marked by a black cross. The purple circle marks a projected distance of 20 arcsec from the galaxy center.
