Note [1]: In order to adjust a particular element a non-zero sigma should
be given for that element. Body ID is required on ALL PLNEPH cards.
Note [2]: Adjustment of keplerian elements is not fully implemented at
the present.
Note [3]: The user may specify a correction EPOCH later than the end of
the arc but not earlier than the start time of the arc.
