You should get the same as the conventional theory
if you enter a distance of zero, a simple check to
start. Then as you increase the distance the
acceleration term will introduce a quadrature
element which will change both the phase and
amplitude. To keep the match to the amplitude, you
can change the orbital inclination or the masses.


NOTE: at zero distance, the photons would arrive from greatly different
directions at all times.

I think zero distance would actually put you (in Henri's model, using his
program) at the center of gravity of the system.

Yes the barycentre is OK to use. The travel time across the orbit is generally
negligible for the purposes of determining bunching and brighness curves.

I suspect the program would yield garbage out (or even crash).

No it doesn't crash, It merely indicates no brightness variation. (actually it
indicates a very variation because I had to add a small corection to avoid a
log(0) situation.

Of course, some would say that there are strong indications that it already
does yield garbage out, for all distances.

You can't laugh at the curves it produces bob. They match perfectly.
