Interesting. Failure of the Karlsson (log(1+z)) model does not invalidate all periodic function predictions. FWIW, Arp & I discussed and disagreed upon both the cause and meaning of the periodic effects - The paper Jacques and I wrote specifically predicts the apparent periodicity is a selection effect, based upon the alpha absorption process, and this effect should fade as the sample becomes more complete. In any case, the observed periodicity should be in multiples ~0.62 - As characterized by Bell & Comeau...Or more correctly, we have tried to explain the observations of B&C.

As I already posted, there are other periodic functions in the Sloan survey.
