  48.    
  49.          SpiceSPK18Subtype     Typedef for enum indicating the 
  50.                                mathematical representation used
  51.                                in an SPK type 18 segment.  Possible
  52.                                values and meanings are:
  54.                                 S18TP0:
  55.  
  56.                                   Hermite interpolation, 12-
  57.                                   element packets containing 
  58.                                   
  59.                                      x,  y,  z,  dx/dt,  dy/dt,  dz/dt, 
  60.                                      vx, vy, vz, dvx/dt, dvy/dt, dvz/dt 
  61.                    
  62.                                   where x, y, z represent Cartesian
  63.                                   position components and vx, vy, vz
  64.                                   represent Cartesian velocity
  65.                                   components.  Note well:  vx, vy, and
  66.                                   vz *are not necessarily equal* to the
  67.                                   time derivatives of x, y, and z.
  68.                                   This packet structure mimics that of
  69.                                   the Rosetta/MEX orbit file from which
  70.                                   the data are taken.
  71.  
  72.                                   Position units are kilometers,
  73.                                   velocity units are kilometers per
  74.                                   second, and acceleration units are
  75.                                   kilometers per second per second.
  78.                                 S18TP1:
  79.   
  80.                                   Lagrange interpolation, 6-
  81.                                   element packets containing 
  83.                                      x,  y,  z,  dx/dt,  dy/dt,  dz/dt
  84.  
  85.                                   where x, y, z represent Cartesian
  86.                                   position components and  vx, vy, vz
  87.                                   represent Cartesian velocity
  88.                                   components.
  89.  
  90.                                   Position units are kilometers;
  91.                                   velocity units are kilometers per
  92.                                   second.
