GC profiles from HST/ACS F606W imaging for the 12 spectroscopically confirmed GCs from Trujillo et al. (2019, grey), the S/N-weighted mean profile of the GCs (blue line), and the mean profile of a star in the images (green). Additionally the vertical dashed red line indicates where the profile is cut and the light blue region indicates where the background has been estimated. The GCs are clearly more extended than the PSF.
