Hi Kevin,

I don't why your method doesn't work but I've successfully used the
following

1. Send an email to JPL's Horizons system requesting osculating
elements. For example, a moment ago I sent this to
horizons@... with a subject of JOB

!$$SOF (ssd) JPL/Horizons Execution Control VARLIST
EMAIL_ADDR = 'jimenez@...'
COMMAND = 'EPOXI'
MAKE_EPHEM = 'YES'
TABLE_TYPE = 'ELEMENTS'
CENTER = 'SUN'
REF_PLANE = 'ECLIPTIC'
START_TIME = '2007-DEC-29 00:00 TDB'
STOP_TIME = '2008-JAN-02'
STEP_SIZE = '5 minutes'
REF_SYSTEM = 'J2000'
OUT_UNITS = 'AU-D'
ELM_LABELS = 'YES'
TP_TYPE = 'ABSOLUTE'
!$$EOF++++++++++++++++++++++++++++++++++++++++++++++++++++++


2. Copy&Paste the reply message into a text file. I named the file
epoxi.ele and saved it into Guide's root directory.


3. Add a line into probes.dat with relevant data
I added

Epoxi@0 @...

The other probes have additional information but Guide does't seem to
mind the truncated version. Remember also to edit the number at line 1
accordingly.


4. Enjoi the fly-by!
A flash movie of the fly-by can be found here:

Kind regards,
Jari
