Hyper-cube plane formed by 3D datacubes. The dimensions of this plane are the different values of the volume filling factor (F_cl = 0.05, 0.3, and 0.6 from top to bottom) and the two metallicities (right column: solar enhanced by rotation; left column: solar without rotational enhancement). Each datacube contains seven Hertzsprung-Russell (H-R) diagrams formed by the models in our grid. We used color-coding to help visualize the H-R diagram corresponding to a β parameter.
