Re: [Ifeffit] Ke

Dear Ke Is there a reason you use first derivative?? I thought if you take second derivative on Athena and then click find zero and then calibrate that value is the correct way. I am learning XAFS myself for the first time and I am novice too. So may be I make no sense but just want to confirm if I am not doing anything wrong. What's your stake in this??

Hello Sin Yuen,

Thanks for forwarding me that study materials on E0.

I use Athena to find the highest peak on the fist derivative of the spectra and pick that value as E0. I think I did not put E0 above this value. I will try to put it on the high energy side to see what will happen.

Tks! Ke
