Which part of "match the velocity curve" did you
miss?

The luminosity variations are purely due to the
eclipses so match the velocity knowing your zero
phase corresponds to the eclipse centres and then
alter the distance. For a small value you will get
a match. As you increase the distance and ADoppler
starts to contribute, the first consequence will be
a shift of phase away from the match. As I said
before, you can try changing yaw and eccentricity
but I think you'll find it distorts the sine curve
too quickly to allow a significant amount of ADoppler.

It's OK. It all fits.

For contact binaries, K is large enough to make VDoppler dominant for
individual photons. The brightness curves are still determined by ADoppler.
