Recreation of the g − r versus absolute magnitude plot from Shi et al. (2017) to determine whether the faint galaxy at the tip of the tail is a low surface brightness galaxy or a UDG. The data points of low surface brightness galaxies and UDGs in Pegasus I and II are taken from Shi et al. (2017). Our candidate (faint galaxy) is depicted as a yellow square box with error bars, which lies in the region populated by UDGs.
