- pw,

It was not my intent to hi-jack Lili Zhang's post. Yes, code for Snyder's 
ISEA is in the zipped file I mentioned.

I've been giving John's code away since 1997. Gerald Evenden, as far as I 
know, is the only person that has done any work with John's software code 
and placed it back into the public domain. I'm perfectly happy to maintain 
custody of the original. I'm also very happy to give out copies to anyone 
that wants it.
