This will not establish a value for c.  You would have
to assume that Maxwell was correct, and the
"ballistic photon" folks do not assume that.

              At this point I am interested only to find out
 if the lightspeed was really found experimentally
constant, using cosmic sources of radiation,
and of course to learn where this information
was published and  accessible for the public.

Yes.  Used in MMX experiments, and yielded a constant.

OK. Now by your knowledge, which of those experiments does not
use 2-way propagation or reflections of light ?
(Reflections falsify the speed of light measurements!)
The DeSitter experiment I have analyzed a while ago and it
seems to me not convincing can not see why would be the
2 half-periods of revolution different, as both have one half
involving
movement in forward direction and another half involving movement
in backward direction.
The MMX experiments use 2-way propagation for the same signals
so do not really matter in my opinion.
That is why I was referring to an experiment using ONLY one-way
propagation of signals/light.





You could use the Moon as a shutter, and if the
CMBR or other high-z source that should be
occulted by the Moon is not occulted at a similar
time as local visible light objects, then you will
have detected an anisotropy.  The 1.3 second
one-way transit time can be multiplied by a (1+z)
of almost 5 for some objects, and more than 1000
for the CMBR.

Might even get to publish a fancy paper or two
on the subject.

     Thanks for the tip!
I am not really interested in publishing now.
I just got this challenge for myself, to understand
how things are with special relativity theory and
the basics of EM theory.  I do not reject anything
from the start and I not accept anything as real
physics without experimental facts.  Even the
experimental facts are subject to interpretation.
For example, I can imagine easily an alternative
interpretation to time-dilation found for the case
of muons.:-)

Good.  Now review all the data of muons measured at different
altitudes, and with systems that use multiple detectors at different
levels, and all yield velocity less than c.

The problem with "special case solutions" is that they fail when you
get away form the special case... and relativity goes a lot further
before it fails.
I am not thinking of a special case solution.
I think that the behaviour of muons could be explained
by considering the increase in the number of internal states
of the muon as a system of components rather than time
dilation. This increase of the mean lifetime is supposed to
follow the increase in
energy, so that the ratio of "disintegration" states to the number
of "relatively stable states" is dropping .
