[Gaussian fitting for the Hinode/EIS mission|https://hyperion.nascom.nasa.gov/svn/eis/release/doc/fitting/eis_auto_fit.pdf]
I am just wondering if there is a complete list of EIS studies available? The list I found online seems to be incomplete.
At line 54 changed one line
Examples for using the routine eis_auto_fit to automatically fit Gaussians across a raster are given in the document below.

The full list is actually available through solarsoft, if you have the EIS branch downloaded. Firing up either eis_xstudy (just lists them) or eis_mk_study (to make and edit them) should give you the chance to load a study. If you're not seeing them, then there's probably one of two problems: either you're set up to use just your personal database ([http://solar-b.nao.ac.jp/hinode_wiki/index.php?fix_zdbase]) and there's nothing there, or you're set up to use the official database, and it's not being pointed to correctly.

We don't distribute it in SSWDB, just in the normal SSW EIS branch, so that shouldn't be a worry.

The studies you found on MSSL hinode/eis website ([http://msslxr.mssl.ucl.ac.uk:8080/SolarB/EisStudies.jsp]) are not complete, however there is a plan to provide complete list of EIS (science) studies online on the website. It is coming soon, so please come back to check it. At the moment, please use "eis_xstudy" or "eis_mk_study" in solarsoft, like David suggested above.

I'm getting first level data from zero level after usual reduction by 'eis_prep'. However, when i am fitting the lines by xcfit, i'm getting the spectrum slightly displaced from the wavelength values given in the data window. What error this will make in the calculations?. Secondly, can we get the accurate width variation ? , and can we use these datas for line-width variation studies ?

*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]
In response to your query we would need more information. Various work has been carried on line widths looking at the differences
at different stages or positions of loops by Hara et al., and Doschek et al (both been submitted), so clearly line widths can
be measured.What variation are you referring to?
