<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am very new to XAFS analysis, I am wondering if there is a
physical meaning to a negative value for SO2. Based on the XAFS equation I can’t
understand what the physical significance of a negative SO2 value would be,
therefore I am assuming that my modeling results using Athena are not representative
of a physically realistic model due to the negative value calculated fro SO2 or
more specifically the amp variable in the guess set. Any insight would be
greatly appreciated.<o:p></o:p></span></font></p>
