A totally unrelated joke: If anyone ever watched "Da Ali G" show on HBO, there was an episode, when Ali G interviews a famous economics professor. The first question was: "Professor, what is a PIN code?"

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. thanks
