[Ifeffit] Is there a Artemis User's Guide like the Athena?

Fri Dec 14 10:17:02 CST 2007

What would be really useful is to make a searchable database with links
to original publications (many of them are more than 20 years old but
are still the best resources on many issues) on many subjects discussed
in this list. 

For example: 

Number of independent data points: see Stern and Heald arcticle in
Handbook on Synchrotron Radiation, Ed Stern PRB article, etc.

Thickness effects: Kim and Stern PRB

Cumulants: G. Bunker, Nucl. Instrum. Methods in 1980s

Background removal: Newville, Livins, PRB etc.

Multiple scattering collinear paths and angular dependence of f(k): Lee
and Pendry PRB (1975?)

Transferability of photoelectron phase: Citrin, Kincaid, et al, Phys Rev
B, 1970s

(I may be wrong in the years and order of authors, but this this the
idea).

It would be so useful if someone (I cannot do it but will be happy to
help) took care of putting together a backbone version of it and set it
up as, say, wiki (which is  Bruce's idea as I once brought it up to
him). I am sure most of us will be happy to contribute references that
we know. Thus, such database may become an exhaustive resource of
information that should be a primer for every XAFS user.

Kefan,

As someone who was in your place 2 years ago, one thing Bruce mentioned
was reading the papers of people you find on the mail list, however he
didn't specifically mention searching the mail list.  When I had
questions, the answers were often already discussed on the mail-list.
If
you're not a member of the mail-list, I highly recommend you join.  As I
currently struggle writing a how-to manual that's supposed to shorten
the
XAFS learning curve for our group, I find myself searching the mail-list
archives often to see how different people approach different issues.

Good luck on your quest!
-Richard
