Yes, this again is used in the main program. It calculates what we
call the Jacobi Integral, which in the restricted Three Body Problem is
a constant value for the whole trajectory from Earth to Mars - the
heliocentric part, when not near Earth or Mars. This is how we can
confirm that the trajectory is accurate; which mine was. It's a very
convenient way to authenticate trajectory calculations like this one.
