ArtPop models of Hedgehog at different distances. We generate these mock galaxies assuming an SSP with an age of 6 Gyr and metallicity of [Fe/H] = −1.75 and place them at different distances but fix the shape and surface brightness. The mock galaxy at 2.4 Mpc visually reproduces both the SBF signal and the integrated color of Hedgehog very well. The two galaxies at 1.8 Mpc and 3.0 Mpc show too strong and too weak SBF signals.
