moon


             xyz = moon(time)  
 
     return position XYZ of the moon relative to center of earth  
     at TIME; the XYZ has leading dimension 3; x is along the vernal  
     equinox, z is ecliptic north.  The corrections to the lunar orbit  
     are from Schlyter (see sch_moon).  Claimed accurate to 2 arc minutes  
     over some reasonable time.  TIME is in days since 0/Jan/00 (that is,  
     0000 UT 31/Dec/99).  This is 1.5 days earlier than the J2000 epoch.
