Definition of the parameter maps

Hi,

There are about a dozen Compute commands that create various beautiful maps.  Some of the parameter maps are not self obvious.  It would be great to have a list of definition and literature reference for those maps.  For example, LI map looks similar to FA map, but I could find out what's difference between the two.   The EV map is generated by ComputeEigVecImage, what is each component in EV map?    That information resource would be very helpful.  

Thanks.
