Looking for reviewers for data reduction chapter
by Scott Calvin 06 Sep '11

06 Sep '11

Hi all, Once again, I have a draft of a chapter of my textbook ready for review. This chapter is on data reduction, including normalization, background subtraction, and Fourier transforms. This will be Chapter 4 in the book, so it should be suitable for near-beginners as well as those with more experience. This is also a chapter where I had to make a lot of decisions on nomenclature and presentation, so experts might be interested as well, particularly if you have strong opinions on that kind of thing! It is a bit more than 40 pages long, which makes it the longest so far. If you are interested in reviewing the chapter and can get feedback to me by 29 September, please contact me directly at SCalvin(a)slc.edu . As always, repeat reviewers are welcome! --Scott Calvin Sarah Lawrence College

Regarding the execution of Demos in PGPLOT
by Rajesh Kumar 06 Sep '11

06 Sep '11

I recently installed 1. PGPLOT 5 (ver: 5.2.2-15) through Synaptic Package Manager from ubuntu - MOTU-Developers (Mathematics, Multiverse) 2. IFEFFIT from Carlo Segre < segre(a)debian.org>, (version 2:1.2.11d-6~lucid0 ) and 3. Horae-07-1 through Synaptic Package Manager from ubuntu - developers (Science, Multiverse) I am not able to run the demo programs. So I started running demo programs for PGPLOT first. My examples are in directory: /usr/share/doc/pgplot5/examples/pgdemo2.f.gz When I compile the program "depgplot10.f" and executed the file, the interaction on the console is attached in the file attached herewith. I need help in this regard and I am very very new to "xafs" as well as ubuntu. Wishing you best of life and time, With regards Rajesh Kumar

Hi all, I have been encountering this problem each time when I run SIXPACK on my sytem. Every time I run SIXPACK it shows the infection due to a worm* * * SIXPACK\MULTIARRAY.PYD,WORM.Z040709.0486.9.* * * Thus, after some time SIXPACK stops running and I have to download it again. I am sorry if I am asking a question already asked on this list but I had searched this on ifeffit mail archieve, but unable to find a similar problem. Kindly help. With thanks Abhijeet Gaur

LCF with different scales
by Hana 03 Sep '11

03 Sep '11

Hi list, I'm looking for a way to make LCF with standards that were measured at different occasions and beam-lines. I did read previous comments regarding this issue, but still need to clarify: 1. Does limiting the range to the smallest range help in this case (if spectra were measured with the same steps size, and a calibration standard was used)? 2. For harder situation; when different steps were used - I found that sixpack (according to its manual) interpolating all spectra to the same energy grid - does this solve the problem? I will be happy to be advised. Thanks, Hana

A simple question regardng the 'chi' in the xmu.dat file (FEFF8)
by Deok-Yong Cho 02 Sep '11

02 Sep '11

Dear Ifeffit users: Hello, I have a simple question regarding the 'chi' in the xmu.dat, an output file of FEFF8. I wish I could get helps from you to resolve this. As far as I know... in the xmu.dat file from Feff6, mu=mu0*(1+'chi') as it should be, but in the xmu.dat file from Feff 8, the 'chi' written in the xmu.dat is a rescaled one by mu0/(mu0 at edge+tens eV) so that mu should be equal to mu0+'chi'. I checked up for FEFF8.4 by turning on and off the FMS card, and found that with the FMS card, mu = mu0+'chi', while without the FMS card, mu is quite close to or same as mu0*(1+'chi') instead of mu0+'chi'. Please help me to find which one is correct. Attached are the Feff.inp and the resultant xmu.dat for ZnO. Thank you all. Best Regards, Deok-Yong Cho Post-doctoral researcher at RWTH Aachen, Germany
