Several spatial models for the GC excess: (a) the J-factor map given the gNFW profile with an inner slope of γ = 1.2, (b) a nonparametric bulge model (B. Coleman et al. 2020), and (c) an X-shaped bulge map (O. Macias et al. 2018; S. D. McDermott et al. 2023). The intensity of the each component is based on the best-fit model given the GC excess template. We do not convolve the maps with the PSF.
