Baryon fraction in four phases: diffuse gas (blue), condensed gas (cyan), hot and warm-hot (red) and stars (green), at level 3 (solid), 2 (dashed), 1 (dash-dotted), and 0 (dotted). In the top panels, the fraction is computed in the full box of each level, and in the bottom panels, it is computed only within the 8.56 Mpc radius of the level 3 box. The differences are then only caused by those in the resolution.
