Re: The Last Word
5708 has a nice line of neutral silicon.
(FWIW, these are wavelengths of spectral lines in the solar spectrum, tabulated in ftp://ftp.noao.edu/fts/linelist/Moore ... Charlotte Moore's old table of lines in the visible part of the solar spectrum. Some numbers are more significant than others. (5708 isn't terrible important. Not like, say, 5007, or 6300, or 6707, or 10830, or 6141, or....)
