-Particulars

   The following integer codes indicate the geometric relationship
   of the three bodies.

   The meaning of the sign of each code is given below.

               Code sign          Meaning
               ---------          ------------------------------
                  > 0             The second ellipsoid is
                                  partially or fully occulted
                                  by the first.

                  < 0             The first ellipsoid is
                                  partially of fully
                                  occulted by the second.

                  = 0             No occultation.

   The meanings of the codes are given below. The variable names
   indicate the type of occultation and which target is in the back.
   For example, SPICE_OCCULT_TOTAL1 represents a total occultation in which
   the first target is in the back (or occulted by) the second target.

         Name                 Code     Meaning
         ------               -----    ------------------------------
         SPICE_OCCULT_TOTAL1   -3      Total occultation of first
                                       target by second.

         SPICE_OCCULT_ANNLR1   -2      Annular occultation of first
                                       target by second.  The second
                                       target does not block the limb
                                       of the first.

         SPICE_OCCULT_PARTL1   -1      Partial occultation of first
                                       target by second target.

         SPICE_OCCULT_NOOCC     0      No occultation or transit:  both
                                       objects are completely visible
                                       to the observer.

         SPICE_OCCULT_PARTL2    1      Partial occultation of second
                                       target by first target.

         SPICE_OCCULT_ANNLR2    2      Annular occultation of second
                                       target by first.

         SPICE_OCCULT_TOTAL2    3      Total occultation of second
                                       target by first.
