EMSAO Night Sky Emission Lines

A substitute line list has been set up in the file rvsao$lib/skylines.dat with all of the bright night sky lines:
4046.56 4040.0 4060.0 15.0 Hg
4358.34 4350.0 4370.0 15.0 Hg
5460.74 5450.0 5470.0 15.0 Hg
5577.35 5570.0 5580.0 15.0 OI
5769.60 5760.0 5780.0 15.0 Hg
5790.66 5780.0 5800.0 15.0 Hg
5890.40 5880.0 5900.0 15.0 Na
6300.23 6290.0 6310.0 15.0 OI
6363.88 6355.0 6375.0 15.0 OI
Column 1 is the center wavelength for the line.

Column 2 is the lower wavelength limit above which the line should be found.

Column 3 us the upper wavelength limit below which the line should be found.

Column 4 has a relative height; when they're all the same this has no effect.

Column 5 gives the element which is emitting.
