Using words astronomical radio annual doppler effect we have: The link:

"It is also possible to infer the position in the sky of a
spacecraft from the Doppler data. This is accomplished by

examining the diurnal variation imparted to the Doppler shift

by the Earth's rotation. As the ground station rotates underneath

a spacecraft, the Doppler shift is modulated by a sinusoid.

The sinusoid's amplitude depends on the declination

angle of the spacecraft and its phase depends upon the right

ascension. These angles can therefore be estimated from a

record of the Doppler shift that is ~at least! of several days

duration. This allows for a determination of the distance to

the spacecraft through the dynamics of spacecraft motion

using standard orbit theory contained in the orbit determination

programs."

On the page 37 is wrote: "At early times the

annual term is largest. During Interval II, the interval of the

large spin-rate change anomaly, coherent oscillation is lost.

During Interval III the oscillation is smaller and begins to die

out."

Who was right: Arago or Vogel?

Once again - they were both right.

Arago attempted to measure a predicted* diurnal variation

It was the annual variation: "In 1818 Arago found that the refraction of a
prism for star light was the
same for light incident in the direction of the earth's orbital velocity vs.
as for that coming in the opposite direction"

in the SPEED of incoming light by measuring a difference in the angle of
refraction for white light. Arago did not measure any difference. He was
right.

Vogel measured a diurnal variation

It was also the annual variation.

in the frequency/wavelength of spectral features as a result of the
movement of the Earth. He was right.

Arago was NOT looking at anything specifically related to spectral
features.

But Brace in 1904 did.


* I assume the prediction was based on a classical analysis of Snell's law
in which the ratio of light speeds in the air and in the block is the same
as the ratio of the (sine of) the angles.

Yes.

The hypothesis (I assume) was that incoming light would have greater speed
when the Earth's movement had his laboratory approaching the source; this
would increase the 'effective refractive index', thus increasing the angle
of refraction. 12 hours later,

The both checked after 6 months.

when there is a relative movement away from the source, the angle of
refraction would be reduced.

Everywhere are the same result: Diurinal effects exsists, annual is null. "
During Interval III the oscillation is smaller and begins to die out."

Stars are at a little long distances than Pionier. And no the annual
oscillations.
Do you agree?
