EIS Data Processing and Analysis
#

Getting started#



Software#

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

IDL> data=obj_new('eis_data',filename)

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.

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

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