Notes. These give the numbers of cells around the sphere in the azimuthal, polar, and radial directions. We also give the total number of cells in each grid and in total. Cells removed by the overlapping grid routines are still included in these counts. See Blakely et al. (2015b) for a more complete version of this table.
