I have no idea which forum this question should go in, so feel free to move it, mods. But I am looking at an astronomy paper containing this symbol, so I'll ask here. What is that symbol that is used to mean "section"? For example: "The relative light curves of XN Mus 1991 were derived in the manner described in (symbol here) 2." meaning "described in section 2." It looks sort of like an sos except vertical. I've seen it in different subjects, not just astronomy. I don't think its greek. What is it called and what font contains it?
