                        <description>2D matrix (MSO lat, MSO lon)
             that defines ion flux. Each
             dimension is separated into 10 
             degree bins. Latitude range: 
             -90, 90 inclusive. Logitude
             range: -180, 180. Matrix is 
             ordered by sequential 36 element
             longitude vectors (elements 0-35 
             are latitude -90, longitude -180
             to 180). Each flux vector can be 
             constructed by multiplying the 
             cell value (magnitude) by the 
             cell normal vector (direction). 
             Each cell normal points away from 
             the center of the unit sphere.</description>
