Consider two pulses transmitted just before and just
after the neutron star passes behind the dwarf as seen
from Earth. This is the point of highest acceleration
and the second catches the first at the maximum rate.



Should not the points of maximun relative velocity for energy from the
neutron star should be when the neutron star is along a line perpendicular
to the line of sight AND passing through the center of the dwarf?

In other words, when the neutron star is furthest from passing behind or
in
front of the dwarf (as seen from earth).

Those are the times when the neutron star is going away from us or
approaching us at maximum velocity.

You said:

E------------------D N (where N is slightly above or below the line of
sight from earth through D)

I say:
N+
|
E------------------D
or |
N-


Or did I misunderstand what you said?

You are perfectly correct in your analysis but I think you
missed that I said the point of highest _acceleration_.

Two consecutive pulses emitted at points N+ and N- will
have almost identical velocities. I am saying the maximum
difference in velocities is when the positions are like this

~N+
E------------------D )
~ N-

The N+ pulse is emitted 1.5ms after the moment of alignment
and it then catches up to the earlier N- pulse which was
emitted 1.5ms before alignment.

The result is that the acceleration term is in quadrature
with the velocity term and the phase of the total relative
to the time of the peak of the Shapiro delay then places a
constraint on Henry's extinction distance.
