      MAG Frame: from http://rbsp.space.umn.edu/data/rbsp/teams/spice/fk/rbsp_general011.tf
      ---------------------------------------------------------

      Definition :

      Geomagnetic - geocentric. Z axis is parallel to the geomagnetic
      dipole axis, positive north. X is in the plane defined by the Z axis
      and the Earth's rotation axis. If N is a unit vector from the Earth's
      center to the north geographic pole, the signs of the X and Y axes are
      given by Y = N x Z, X = Y x Z.. See Russell, 1971
      

      The implementation of this frame is complicated in that the definition
      of the IGRF dipole is a function of time and the IGRF model cannot be
      directly incorporated into Spice. However, Spice does allow one to define
      time dependent Euler angles. Meaning, you can define an Euler angle
      that rotates GEO to MAG for a given ephemeris time t:

         V           = r(t) * V
          GEI                  MAG
      
      where r(t) is a time dependent Euler angle representation of a
      rotation. Spice allows for the time dependence to be represented by a
      polynomial expansion. This expansion can be fit using the IGRF model,
      thus representing the IGRF dipole axis.

      IGRF-11 (the 11th version) was fit for the period of 1990-2020, which
      should encompass the mission and will also make this kernel useful for
      performing Magnetic dipole frame transformations for the 1990's and
      the 2000's. However, IGRF-11 is not as accurate for this entire time
      interval. The years between 1945-2005 are labeled definitive, although
      only back to 1990 was used in the polynomial fit. 2005-2010 is
      provisional, and may change with IGRF-12. 2010-2015 was only a
      prediction. Beyond 2015, the predict is so far in the future as to not
      be valid. So to make the polynomials behave nicely in this region (in
      case someone does try to use this frame during that time), the
      2015 prediction was extended until 2020. So for low precision, this
      kernel can be used for the years 2015-2020. Any times less than 1990
      and greater than 2020 were not used in the fit, and therefore may be
      vastly incorrect as the polynomials may diverge outside of this region.
      These coefficients will be refit when IGRF-12 is released.
      
      Also, since the rest of the magnetic dipole frames are defined from
      this one, similar time ranges should be used for those frames.

                  Definitive           Provisional   Predict    Not Valid
       |------------------------------|+++++++++++|###########|???????????|

      In addition to the error inherit in the model itself, the polynomial
      expansion cannot perfectly be fit the IGRF dipole. The maximum error
      on the fit is .2 milliradians, or .01 degrees. 

      The MAG frame is achieved by first rotating the GEO frame about Z by
      the longitude degrees, and then rotating about the Y axis by the
      amount of latitude. This matches the new frame to Russell's definition.

				RTN Frame is defined as follows:
                    - R is positive from the Sun to the spacecraft.
                    - T is omega cross R, where omega is the sun spin axis.
                    - N is R cross T, which completes the right-handed system.
					
					This frame assumes the instantaneous center is located at the Sun,
                        and not the spacecraft. Further, the axes are associated
                        with the normal X, Y, and Z in the following manner:
                     
					- R -> X
					- T -> Y
					- N -> Z
