I will discuss my summer project undertaken at Gemini South with Juan Madrid. Using data from the Hubble Space Telescope Advanced Camera for Surveys, we detected globular cluster candidates using an automated process and narrowed them down by their photometric properties and visual inspection. The colour-magnitude diagrams, globular cluster luminosity functions, and radial distributions were created, and the specific frequencies calculated. I will discuss these results.
