In the 2D radial plane, we achieve a large ground state fidelity for the entire procedure (loading and cooling) of $\\sim$0.73, while the ground state occupancy is $\\sim$0.88 for realizations with a single atom present. For 1D axial cooling, we attain a ground state fraction of $\\sim$0.52. The combined 3D cooling provides a ground state population of $\\sim$0.11.
