!Gaussian fitting

The document below details software available in the EIS Solarsoft tree for fitting Gaussians to EIS data.

[Gaussian fitting for the Hinode/EIS mission|https://hyperion.nascom.nasa.gov/svn/eis/release/doc/fitting/eis_auto_fit.pdf]

Examples for using the routine eis_auto_fit to automatically fit Gaussians across a raster are given in the document below.

*Suguru Kamio has uploaded an [EIS spectral atlas|eis_atlas.pdf], using data from Charlie Brown's line list paper. Best suited to A0 paper, but readable as a PDF. \\Other resource of EIS Spectral Atlases can be found [here|http://solar.bnsc.rl.ac.uk/ralsolphys/eis_ral.html] or directly access a few PS file: [Active region|http://solar.bnsc.rl.ac.uk/%7Eyoung/solarb_eis/atlas/eis_spec2.ps];   [Quiet Sun|http://solar.bnsc.rl.ac.uk/%7Eyoung/solarb_eis/atlas/eis_qs_spectrum.ps];   [Flare|http://solar.bnsc.rl.ac.uk/%7Eyoung/solarb_eis/atlas/flare_spec.ps]
