Citation for SPIE journals (Lyx with RevTex 4)

It took me a while to figure how to properly generate citations for a manuscript for SPIE. The following is for Lyx 1.6.

Document class: “article (REVTeX 4)”
Custom class options: “supercite, prb,nobibnotes”
“supercite” causes superscripts to be used at the list of cited sources
“prb” causes superscripts to be used for in-document citations
“nobibnotes” causes author footnotes to appear on the first page, rather together with the bibliography
“altaffilletter” causes letters to be used for super scripts in the text.
Bibliography: “NatBib”
To make something like “In Ref. 4,…” to appear in text, use ERT of \nocite{citekey}.

These might not be the “correct” setting, but it works for my case.
