Hi All, I'm trying to find my way into XAFS data processing with Athena, but I'm new to the topic. I hope someone can help me out with my questions. As background information: Currently I'm planning my beamtime experiment for XANES spectra about phosphorus speciation at SLRI in Thailand. I have made a tutorial with data from Bruce Ravel from scans of Lepidocrocite. I have a question regarding this data. For example in the header information of file Fe_lepidocrocite.000 (from Bruce Ravel's github site) there can be found the abbreviations SRB, SRSS and SPP. So my first question is: What do this abbreviations stand for? SRB is the sampling range (SR..?!), i guess, so what does 15k stand for (data ends at 7971.35723 keV, but how is this connected to "15k"?)? SRSS manages the step size (..SS?), but how does "0.05k" result in the given steps? I assume that this kind of "k"-settings may be limited to X-23A2 beamline (or BNL), but still I'm anxious to know how the data has been collected. Best regards, Florian
