Hi Matthew, Thanks for your ideas and even more for the spectra. I looked at the ESRF data base before, but forgot to mention it in my original email. We tried our best to avoid radiation damage and found little-to-no evidence of it in our samples when we compared our standards (a series of iron

Dear Don. Regarding yours of Fri, 08 Jun 2018 09:54:40 -0400: ESRF has a dbase of S XANES, but they're all pretty affected by overabsorption ("self-absorption"). I think the only reliable way to take such data is in TEY mode. There's a spectrum there for cinnabar (remember, there are multiple

Hi Don, I am sure you are aware but I would like to remind you that the sulfides that you are working with have serious potential for self absorption. Most spectra out there have different degrees of self absorption which can really mess up LCA type analysis. This is not a quick solution, but y

Dear Vadim, I am running myself Demeter 0.9.26, 64bit under win10 and do not have such trouble. But your description is similar to the problem occurring with the previous release of Demeter 0.9.26 pre2 (old path for gnuplot executable in ini file leading the same effect), did you download the act

Hello All, First let me apologize if the question below is inappropriate for this group, but I don't know of a better set of experts that I can ask. So, here is some background: I have some old S K-edge XANES data from NSLS X15B for S-bearing silicate glasses that was collected by a Ph.D. stu
