   This kernel contains high-accuracy lunar orientation data from the
   JPL Solar System Dynamics Group's planetary ephemeris DE440.
 
   The DE440 ephemeris is documented in
 
       [1] Ryan S. Park, et al, "The JPL Planetary and Lunar Ephemerides
           DE440 and DE441," The Astronomical Journal, Volume 161, Number 3.

   Applications using this file must also load the NAIF lunar frame kernel
 
      moon_de440_200625.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.
 
   This PCK file, when used together with cited frame kernel, provides the
   orientation of the lunar Principal Axes (PA) reference frame defined by
   DE440, relative to the ICRF.
 
   These kernels, used together, also provide the orientation relative to the
   ICRF of a variant of the Mean Earth/Polar Axis (ME) reference frame, which
   has been defined to align closely with the DE421 ME reference frame. See
   [1] for a description of this reference frame.
 
   See the cited frame kernel for the names and ID codes used by the SPICE
   system for these reference frames.
