Jean Meeus' "Astronomical Algorithms" is a good book to find this sort
of thing, along with "Fundamental Ephemeris Computations" by Paul
Heafner.

Ian, 
I've read the "Fundamental Ephemeris Computations", it gives general
information about the DE405 and again programs to do the calculation
but not the formula.
I will check for Jean Meeus' book.
Thanks for the info.
