Dear all,

This spring I need to supervise some undergraduate students during a
4-week project in my research group. I would like to introduce them
into the world of data processing with athena and sixpack. I would
like to find a tutorial for sixpack and some test data on principal
component analysis and linear combination fitting before giving them
some of my own data. Can anybody help me ? Or anybody else had to
teach something similar, any idea would help!

Thank you very much in advance,

Have a great 2012

PJ Sabbe

Hi Pieter-Jan,

The "EXAFS Divination Set" should work as test data, although I haven't tried PCA on it: http://www.xafs.org/EXAFS_Divination_Set

Feel free to contact me for follow-up if you'd like to know more about that set, etc..

Pieter-Jan,

There is a ton of useful stuff and useful links at
http://xafs.org/Tutorials, including much written by folks whose
names you'll recognize from this mailing list.

Hi all,
I am dealing with some spectra of Er and Yb in the K-edge.
Does somebody was doing the deconvolution of the spectra in these energies?
I will appreciate all the help to treat the spectra in this high energy
regions.
Kind regards, euG

This might be what you are looking for:

http://dx.doi.org/10.1088/0953-4075/33/15/301

A little bit of time with google scholar turns up a bunch of other
results in both energy and R space.
