  • $\begingroup$ I made an effort looking at academic.oup.com/mnras/article/469/1/744/3737674 . I got stumped on the meaning of the variable (in script format) Q. Whatever the discussion in this article is, this variable seems to be the critical element. There also seems to be a lot of references to Buchert. I recommend you try to locate these references and search for the (script) Q. I also found the article en.wikipedia.org/wiki/Coherence_length , but it did not use the notation Q. $\endgroup$
