The table displays:
-- 3*3 matrix of its own moments of inertia (in rows <b> 1:1, 2:1</b> and <b>3:1</b>) and
-- the main (principal) moments of inertia (in row <b>IX & IY & IZ</b>)
+ - 3*3 matrix of its own moments of inertia (in cells <b>i:j</b>) and
+ - the main (principal) moments of inertia <b>Ip1</b>, <b>Ip2</b> and <b>Ip3</b>
\note The matrix of inertia is returned in the central coordinate
system (G, Gx, Gy, Gz) where G is the centre of mass of the system
