Digging at NTRS (NASA Technical reports).
Looked up the formulae for guidance (the code was written in Fortran in 1977, uses RK4 to get to the point), attitude control laws, and sail thermal constraints. Some of the formulas will be available in the source as soon as I upload Precession MFD to O-H. It already has instant killrot (cheating!), now I want to forego the difficulties of attitude control/stabilization and implement (via MFD) instant selection of cone and clock angles. Would be nice to organize a small Earth-to-the-Moon challenge...
