   This kernel contains high-accuracy lunar orientation data from the
   JPL Solar System Dynamics Group's planetary ephemeris DE-421.
 
   This file supersedes the binary lunar PCK
 
      moon_pa_de418_1950-2050.bpc
 
   Applications using this file must also load the NAIF lunar
   frame kernel
 
      moon_080317.tf
 
   which contains frame specifications required in order to use this
   PCK file. See this frame kernel for detailed documentation
   describing the lunar body-fixed frames supported by SPICE. Also see
   that kernel for a code example illustrating use of this PCK file.
 
   This file, when used together with cited frame kernel, provides the
   orientation of the lunar Principal Axis (PA) and Mean Earth/Polar
   Axis (ME) reference frames defined by DE-421, relative to the ICRF.
 
   The data in this PCK actually describe the orientation of the DE-421
   PA frame, but these data are not easily usable by SPICE unless the
   cited frame kernel is loaded.
 
   This file covers the time period shown below:
