Name and cite specific figures/results of related work Currently I am writing a paper and would like to cite specific things in the related work section of other papers.

Would this be legit?

Basically I do not need the most stuff out of this paper which I want to cite, just this one figure, equation and their explanation why this happened. The main research in that paper is irrelevant for me.
