The global data set will of course further illuminate the mantle wavespeed structure so this acts to show the areas better resolved using the new data. Regions where the mask is on (i.e. equal to 1) are regions of lower confidence or poor illumination. Regions where the mask is off (i.e. equal to 0) are regions of higher confidence or good illumination. The 3D grid contains the columns: depth (km), latitude (deg), longitude (deg), mask on (1/0)." ;
