!Gaussian fitting

For automatically fitting a Gaussian to an emission line over an entire raster and analysing the results, the following routines are available:

*[EIS_AUTO_FIT|AutoFit]

*[Viewing the fits - EIS_FIT_VIEWER|FitViewer]

*[Correcting fits for slit tilt|CorrectSlitTilt]

*[Correcting fits for orbital variation|CorrectOrbitVariation]

Automatic multi-Gaussian fits are now possible with the routine eis_auto_fit_gen. The tutorial below describes how to use it. 

* [Tutorial for using eis_auto_fit_gen|eis_auto_fit_gen.pdf]

If you want to average a spatial region and fit multiple lines in the spectrum, then the following tutorials describe available software:

*[Tutorial for spatially-averaging spectra|gauss_pixel_masks.pdf]
