I did an answer to a similar question before I though.
In the simplest case you need a number galaxies in nearly the same direction. Then taking the measured redshifts you perform a type of spectral analysis. The simplest method is to consider a test periodicity such as 72 km/s and to then take the remainders of the redshifts after removing multiples of 72 km/s. If you plot a histogram of the remainders from each galaxy, the null hypothesis is that they will be randomly distributed. If there is a periodicity then they should be heaped up in a smaller region of the range. By varying the test periodicity in small increments and plotting the resulting heaping up, you get a graph that has peaks at the potentially valid periods. These need to be tested for significance.
My description is trying to make clear the idea. There are simpler mathematical ways of doing it, even in a spreadsheet, that give a sensible measure. The result is very similar to a spectrum from either a spectrometer or a spectral analysis like FFT. |
Thanks for the clarification.
However, it seems that your method is quite different from the one Tifft reported using, to arrive at conclusions about redshift quantisation, in his 1978 paper.
For example:

The third and most serious complication in a large-scale study of the discrete redshift is the fact that galaxies are in general blends of several redshift states, as discussed in DSR1. An observed mean redshift of a galaxy can in principle lie anywhere between state values, depending on the number and distribution of states present. To get around the blending of states, [...], one must have a considerable number of accurate, detailed data. Such data exist for very few galaxies and are clearly insufficient for the problem.

So, I will ask my question again:
Given a perfectly accurate redshift of a galaxy (we'll look at definitions later),
which Tifft declares to be not a "monostate", how is a specific redshift period/quantum determined?
This time I have highlighted a key part of the question which you seem to have overlooked.
Please explain, in detail, how a specific redshift period/quantum can be extracted from the "
observed mean redshift of a galaxy" (which galaxy is not a monostate), given that (in Tifft's model) this observed redshift "
can in principle lie anywhere between state values, depending on the number and distribution of states present" (my bold).
