Dear all,

I am new in this group so I don't know if this is the right place to ask about it, but I´d like to know about LCF performed with Athena in XANES data. I had some difficulties in founding information about errors reported by the program.

I am working with different techniques and in some cases I have to calculate uncertainty in results reported. In LCF results reported by Athena I don't know how to interpret the errors reported between parenthesis along with each model spectra.

In my reports I carefully define if I am reporting the standard deviation of the mean, a combined standard uncertainty,etc. depending each case, the coverage probability, etc. So I need to understand the information Athena is reporting as errors in LCF.

So grateful if anyone can help me with this issue.

Best regards.

Dear all

How can texture in a powder sample be modeled in ARTEMIS?

My samples are fine powders of a layered material, mixed with cellulose and pressed to pellets. The data were collected in fluorescence mode with a 45 degree tilt.

PXRD data reveal that the samples are highly textured, including standards.

I am new to XAFS, and I need some advise to deal with this issue.

Best regards

Kirstine Dalgaard
