George, you whole argument is based on the shapiro delay peak being 90
out of
phase from the velocity peak.

In our language, that means there is an anomalous increase in pulse
separation
90 degree before the velocity maximum.

Almost, it means an increase in separation during the few
degrees prior to 90 and a rapid switch to an anomalous
decrease during the few degrees just after 90.

I think you are misinterpreting the graph.
How could one side be different from the other.

We discussed that before, frequency is the derivative of
time delay, or see Leonard's more detailed explanation.
It is that sudden change from an anomalous increase to
a decrease that I think will be difficult to reconcile
with the smoother curves of the low eccentricity
solutions.

Yet the major axis lies at 35 degrees from the LOS. CMIIW.
If that is true and the orbit is actually elliptical, then the peak
radial
velocity might not occur at the side but maybe 20 degrees before it.

Yes, I asked you about the effect of an elliptical orbit
some days ago but you said that rather than causing a
phase shift it made the sinewave asymetric. By all means
revisit that idea, it is what I expected you to suggest.

It will only create a sine wave if the yaw angle is nearly zero.

OK, so you are saying you cannot create a phase-shifted
sine wave using yaw, I am content to accept that for the
moment. In that case you cannot use yaw to cancel out a
phase shift of the TDoppler caused by the addition of a
significant amount of ADoppler to the larger VDoppler
and that means you can figure out an upper limit for
the speed equalisation distance. My rough calculation is
of the order of a light minute.

However, neither Leonard nor I could understand why you
think variations in luminosity of the dwarf can delay
pulses from the pulsar. I see you have commented on
that in another reply about "reflections" from the dwarf
which obviously isn't the case. I'll leave Leonard to
deal with that nonsense.

I didn't mean it like that.

OK.

There are many possibilities as to how the presence of a companion might
affect
the pulse rate of the star. Shapiro is only one..

Many? Tell me some. AFAIK there is nothing else.
