γ-ray flux maps from simulated NSs within 1 kpc in Galactic coordinates. The flux is computed assuming a MSP luminosity of ⟨L⟩ ∼ 1 × 10³³ erg/s (left), ⟨L⟩ ∼ 4 × 10³³ erg/s (middle), and ⟨L⟩ ∼ 8 × 10³³ erg/s (right), scaled by empirical factors for observed GCs (top), disrupted GCs (middle), and the combination of both populations (bottom). The colour scale indicates the total γ-ray flux in each bin, shown on a logarithmic scale between 10⁻¹² and 10⁻¹⁶ erg s⁻¹ cm⁻². To obtain a smoother flux map, we applied a Gaussian filter with a smoothing parameter of σ = 1, which corresponds to a smoothing scale of approximately 0.5°.
