Hiroshi,

Here is one explanation from the mailing list:
http://millenia.cars.aps.anl.gov/pipermail/ifeffit/2002-October/000141.htm

Matt's followup is also very helpful:
http://millenia.cars.aps.anl.gov/pipermail/ifeffit/2002-October/000142.html
 
Pages 6 through 15 of the talk that I gave at the APS XAFS summer school last 
August are relevant to the last paragraph from the first link:

Hope that helps,
B
