Fig. 1.
Illustration of the MGE modelling used to create residual images in which GCs were detected. Left: collapsed MUSE image of FCC 147. Black and red contours illustrate isophotes of the original image and the MGE model, respectively. Middle: residual image after subtracting the model from the image. Otherwise hidden point sources are now visible. Right: residual with GC highlighted. Red triangles show the position of GC candidates from the ACSFCS catalogue (Jordán et al. 2015). The blue circles show the position of confirmed F3D GCs in FCC 147.
