Orientation constants for Comet 9P/Tempel 1
--------------------------------------------------------
 
     The inertial reference frame for these constants is J2000; this is
     the default reference frame for PCK orientation data.
 
     The epoch of the constants is the Julian ephemeris date (JED) 
     2453555.740027.
 
     The NAIF integer code for 9P/Tempel 1 is 1000093. See the NAIF_IDs
     required reading for further information on NAIF integer codes.
 
     The 9P/Tempel 1 RA and DEC constants below are from [1].

     The 9P/Tempel 1 W terms below are from comments in [1]:

                     .                       2    2               2
        W = 109.7,   W = 211.849 deg/day,   d W/dt = 0.024 deg/day

     These constants are applicable for Deep Impact Tempel 1 encounter, 
     4 July 2005.
