Are you sure?  Broadhurst et. al.'s Nature paper is about peaks in
the power spectrum, but that's not what I was talking about, as I
tried to make clear some time ago.  Tifft and company (papers in the
Astrophysical Journal) seem to claim that there are exactly 
quantized redshifts in units of 12.07 km/s.

I know this.  I'm not sure what Tifft thinks, 'cause he doesn't
do irrational multiples (that's the "quantization").  At least, so
it seems; his papers are none too clear.

>Having said that, i think the claimed peaks probably don't exist.

I heard from a friend that somebody, he can't remember who, says the
Broadhurst result goes away if you do different binning.  I think
there is unspoken agreement that the Tifft results are not worth
spending time worrying about.
