    Re: Lewis and Clark lunars: a request for help.

    Dear George,
    
    do you need a program or do you need just accurate data? In the second case
    I would try the Jet Propulsion Laboratory site "HORIZONS" which provides
    "access to key solar system data and flexible production of highly accurate
    ephemerides for solar system objects (163000+ asteroids and comets, 128
    natural satellites, 9 planets, the Sun, L1, L2, select spacecraft, and
    system barycenters)" (their description) from 3000 B.C. to 3000 A.D.
    (http://horizons.jpl.nasa.gov/horizons.html). I have used it to calculate
    values for solar declination to compare with the tables in the early
    navigation manuals and that was most useful.
    
    Regards,
    
    Wolfgang
