:"Using more than 200 redshifts in Coma, Perseus, and A2199, the presence of a distinct band-related periodicity in redshifts is indicated. Finally, a new sample of accurate redshifts of bright [[Coma cluster of galaxies|Coma galaxies]] on a single band is presented, which shows a strong redshift periodicity of 220 km s⁻¹. An upper limit of 20 km s⁻¹ is placed on the internal Doppler redshift component of motion in the Coma cluster".<ref>{{cite journal |last=Tifft |first=W.

Tifft, now Professor Emeritus at the [[University of Arizona]], suggested that this observation conflicted with standard cosmological scenarios. He states in summary:

:"Throughout the development of the program it has seemed increasingly clear that the redshift has properties inconsistent with a simple velocity and/or cosmic scale change interpretation. Various implications have been pointed out from time to time, but basically the work is observationally driven."<ref>{{cite journal |last=Tifft |first=W .G. |date=1995 |title=Redshift Quantization - A Review |journal=[[Astrophysics and Space Science]] |volume=227 |issue=1–2 |pages=25–39 |bibcode=1995Ap&SS.227...25T |doi=10.1007/BF00678064|s2cid=189849264 }}</ref>
