Re: [Ifeffit] Basic questions about the preliminary data processing in Athena

Hi, Carlo, Thanks for your physical explanation for the calibration. I have another question. I measured the same element at different beamlines. So if I want to compare different samples measured at different beamlines, how should I do for this situation given the possible different calibration

Re: [Ifeffit] LCF on Larch - EXAFS Region

Hi Martin and Mike, Thanks -- I'll take a closer look at your paper on this! I think we all basically agree that linear analysis of EXAFS can work, but also that compared to linear analysis of XANES, linear analysis of EXAFS has a few more caveats and issues that need to be addressed for each

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

[Ifeffit] Modelling texture in Artemis

2018-08-14 Thread Kirstine Dalgaard
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,

Hi Matt I recently had some problems incorporating the larch Cauchy wavelet transform into my program for rapid bulk processing of QEXAFS data (discussed http://millenia.cars.aps.anl.gov/pipermail/ifeffit/2014-April/007250.html). I particular after importing the relevant module into python the
