On or about Sat, 15 Oct 2005 18:15:56 GMT did "Androcles" <Androcles@ MyPlace.org> dribble thusly: >"The spectral class [of stars] is determined by the relative positions >and intensities > of the absorption lines, and these are unaffected by a Doppler shift." >'Nuff said, nobody could top that, not even Tom Roberts with his >observation It's a completely correct statement. Though it does require that one be familiar with the term "relative", understand what it means, and grasp the rather significant effect upon meaning it has in the above statement. Absorption lines as a whole are *SHIFTED*, not spread out, which is a paraphrase of what's said above. -- - Mike Ignore the Python in me to send e-mail.
