An EIS FITS file is read into an IDL object with:

where 'filename' is the name of the level-1 file (a level-0 file can be read in the same way). Information can be extracted from the object via a large number of [object methods|EISmethods].
You can find out where EIS was observing by going to:

!Gaussian fitting

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

At line 52 changed one line
[Gaussian fitting for the Hinode/EIS mission|https://hyperion.nascom.nasa.gov/svn/eis/release/doc/fitting/eis_auto_fit.pdf]
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.
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.
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.

%%tab-Line width variation studies by EIS
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 ?
