Paul you have exactly espoused the position as MS presents. It is this which I
reject for the following reason..
Forget frequency versus spectrum which is a band of frequencies. I know that
certain spectral lines are associated with specific elements. But this is worh
questioning:
Since it is known from unambiguous examples what the specific frequencies of
particular lines are, even if the pattern is shifted towards the red or the
blue end of the spectrum, the original specific frequencies can be identified.
but this is my point entirely. There is no way of knowing from an ambiguous
example such as a distant star, whether the more violet light or the more red
is due to a doppler effect, or is it its natural colors due to either unique
elements or temperature .
I am hoping that what you call unambiguous examples are observations made on
earth, and not our sun, from which we can safely assume no element samples have
been obtained for verification.
I will need to get back to you on the Fraunhofer lines

May I just ask what are pertinent to me a couple of questions re doppler
shift.
To be able to evaluate anything from doppler shift three things need to be
known with certainty.
1. The original stationary frequency of the EMR source.
I'm dredging this up from memory but I think it is reasonally accurate.
The process involves a spectrum not just a frequency. Coulped with this
'rainbow' is a phenomenon named Fraunhofer Lines which are absorbtion by known
elements in the atmosphere of stars. This absorbtion manifests as dark lines in
the spectrum of the star, and because these lines are associated with known
elements they appear at the same relative position in the spectrum of all stars.
The pattern thus is as characteristic as the growth rings in trees being
associated with the climatic conditions pertaining at the time of their growth.
Just as the patttern in a set of rings near the outer surface of one tree can
be shown to have occurred at the same time as a similar set of rings in the
middle rings of another tree, so the spacing of Fraunhofer lines present a
pattern which permits the identification of the specific line in a spectrum.
Since it is known from unambiguous examples what the specific frequencies of
particular lines are, even if the pattern is shifted towards the red or the
blue end of the spectrum, the original specific frequencies can be identified.
The degree and direction by which the pattern is shifted thus indicates the
direction and velocity of the source.
Good old Wiki (plus many others) will help --
