[Ifeffit] CN and bond distances in Artemis

[Carlo Segre]

Hi Juan Antonio:

It looks like this is fluorescence data.  It is likely that you have 
significant self-absorption if this is a Pt foil.  Try to apply an 
"infinite" sample correction to this data before fitting.  That should 
correct the SO2 somewhat.  A much better thing to do is to take this data 
in transmission.  i suspect that if it is a standard foil, it is optimized 
for transmission and should be measured in that mode.
