The set of [IDL map software|http://beauty.nascom.nasa.gov/~zarro/idl/maps/maps.html] of D. Zarro is a popular means for handling solar image data. The situation is more complicated for EIS than imaging instruments as an image can be an intensity, velocity or line width map. EIS maps are generated from EIS data objects as follows (in the case of a velocity map from Fe XII 195.12):
IDL> obj=obj_new('eis_data', filename)\\
IDL> m=obj_new('eis_moment',obj,iwin=195.12)\\
IDL> mmap=m->mk_eis_map(195.12,/vel)
The output mmap is in the standard format accepted by the map software.
To generate an intensity map use keyword /int and for a line width map use /wid. When the 'eis_moment' object is created (step 2) a widget will pop up allowing you to define the spectral region containing the emission line. Moments are used to generate the velocity and line widths which ensures quick results. You can use Gaussian fitting by giving the additional keyword fit='gauss' in step 2 for the eis_moment call.
