CAUTION  CAUTION  CAUTION!!!
 
The source file, plu008.nio, was created by Bob Jacobson per (indirect)
request of Larry Wasserman of Lowell Observatory. Larry wanted a Charon
ephemeris that included Tholen's latest HST-based observations; this does.
 
But Jacobson says this short arc solution does NOT include all the "regular"
Charon data, and so should not be taken as a general replacement for plu006.
(I'm not aware of a plu007 solution.)

Comments:
Special ephemeris based on Tholen's HST short arc fit.  This does NOT
replace the current ephemeris for general use.
