Arago vs Vogel

I have found the two old measurements:
"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. This unexpected null result
was explained that same year by Fresnel's ether-dray theory, which assumed
partial ether entrainment in transparent media by an amount depending upon
the first power of v." From: http://www.3rd1000.com/chronoatoms.htm

And:

2. Vogel, H. C., "On the spectrographic method of determining the velocity
of
stars in the line of sight", Monthly Notices of the Royal Astronomical
Society, Vol. 52, p.87, 1891
"The first result of any importance which the spectrographic method
furnished was the proof of the influence of the Earth's motion on the
displacement, which the earlier direct observations had failed to show
with certainity. [...]" From:

Who was right: Arago or Vogel?
