| Documentation | File units : kg-m**2/s 1. The tabulated date corresponds to the midpoint of the 1-day-long averaging interval. 2. The mean has been removed from the tabulated OAM values. The mean OAM mass term (kg-m**2/s; x,y,z) = 1.35701772E+29 1.02514762E+29 2.93920693E+30 The mean OAM motion term (kg-m**2/s; x,y,z) = -1.05234946E+24 6.09465573E+23 9.85695694E+24 |
