The speed of light c is considered to be a constant since at least
Maxwell. However, Michelson and Morley, in the mathematics underlying
their interferometer experiment (MMX) to find evidence of the ether,
used expressions like c+v and c-v. Their idea was that the formula
(c+v +c-v)/2=c applied overall and that the components of this formula
should be applied separately to the upwind and downwind paths.

The expressions c-v and c+v are not well received or understood in
this NG. This is because it could lead to the idea that the speed of
light is subject to the speed of the source and this is anathema to
relativity supporters. However, the two expressions have a real
validity. They are mathematical devices to account for the target
moving away or towards the source. While the speed of light is always
c, the distance between source and target will vary with the motion of
objects through space. To compensate for these variations, c-v and c+v
are used. MMX is a good example to explain it. The interferometer used
in MMX is attached to the earth. The earth moves through space. A
light beam is sent from a source through the beam splitter of the
interferometer to the mirror at the other end of the parallel arm of
the equipment. The distance between beam splitter and mirror is 11m as
measured in the lab but the earth does not stand still. It and the
mirror move away from the location where the beam splitter was at the
time the light beam passed through it. By the time the light has
caught up with the mirror, it has moved on to a new location, widening
the lab distance of 11m to a distance through space of 11m+. To allow
for this extra distance, the speed of light has to be adjusted to c-v
or 300000km/sec-30km/sec giving an effective 299970km/sec. Likewise,
on the return trip, the speed of light has to be adjusted to c+v or
300000km/sec+30km/sec giving an effective 300030km/sec to account for
the fact that the beam splitter is moving towards the light beam
reflected from the mirror. In short, the EFFECTIVE speed of light is
subject to the motion of the target (30km/sec around the sun) but the
ACTUAL speed of light up and down the parallel arm of the
interferometer is always (c+v+c-v)/2 = c. If you understand this there
is no need to worry that the speed of light is not c.

Very good summary Peter,
But the truth at the end is light is observer dependant in speed.
It is constant from source, but not for the observer.
There is no way any speed (no matter if it is constant from the source)
can be the same speed to all observers.
This is a big part of relativity that many relativists refuse to
admit and simply must ignore since they can not handle a non
constant speed of light.
But, it is constant from the source even if the source is moving,
but is not constant to the reflection point if moving because
waves do not do such and that is why we get doppler shifts
in light and sound and water waves.
The observers speed measurement of the waves is relative
to the lightwaves.
Simple as that.

Spaceman,
I agree but I am stuck trying to explain the origin of c+v and c-v.
Androcles thinks there is something odd about c+v and c-v. He is
collecting opinions about it which does reveal the depth of ignorance
and parrotlike adherence to dogma of some posters.
