Thanks, the writing alone on that other one was atrocious.

  Precisely ! Fe XXV ? That sounds a bit like descendent from a long line of monarchs.

    NASA site spells it the same. Presumably it's how physicists call ions.

      I learned to spell ions like that in highschool, though never more than Fe III, I think.

    I also thought that FE XXV was a misspelling, or bad use of notation. But it's (apparently) the usual notation in spectroscopy. http://www.nist.gov/data/PDFfiles/jpcrd200.pdf http://www.nist.gov/data/PDFfiles/jpcrd200.pdf FE I is not ionized Fe (26 protons, 26 electrons, 0 net charge) FE II is ionized Fe (26 protons, 25 electrons, +1 net charge) FE III is not ionized Fe (26 protons, 24 electrons, +2 net charge) ... FE XXV has (26 protons, 2 electrons, +24 net charge) FE XXVI has (26 protons, 1 electron, +25 net charge) -- This is not the standard chemical notation. In chemistry: FE II is ionized Fe++ (26 protons, 24 electrons, +2 net charge) FE III is ionized Fe+++ (26 protons, 23 electrons, +3 net charge)

  > First of all, it's not necessary to use a word such as "menagerie" in any article, apparently it's being used incorrectly anyways, it means "a collection of animals". A commonly used secondary definition of menagerie is "a strange or diverse collection of people or things."

Thanks. We changed to that from http://thewatchers.adorraeli.com/2014/07/25/mysterious-signal-from-the-center-of-the-perseus-cluster-unexplained-by-known-physics http://thewatchers.adorraeli.com/2014/07/25/mysterious-signa....
