Dear XAFS community members,
I have a question concerning data merge. We normally collect XAFS data in
both transmission mode and fluorescence mode. We normally have to merge a
few scans to enhance signal-to-noise ratio. For one
I have a question of the FEFF8 installation in IFEFFIT on a window XP.
I know that the IFEFFIT includes FEFF6, and I have the licence of FEFF8.
I have used IFEFFIT with FEFF6 on the window and FEFF8 in a LINUX system.
Now I want to use the FEFF6 on the windos XP.
After I unzipped the ifeffit
Dear Fiona,
I think it would be pretty unusual for transmission and fluorescence
data measured at the same time to be of comparable quality and both be
noisy-but-good-enough that merging would actually help. Are you
sure that the data a similar enough (no pinhole or self-absorption
effects) that
A trick I've used when the fluorescence data are good but affected by
overabsorption, and the transmission data are noisy is to
reduce both data sets to post-edge normalized form (0 in pre-edge, oscillating
about 1 post-edge), then apply a simple
overabsorption model to 'correct' the
