Possible problems with athena
Hello all, I am using the latest version of Demeter (@0.9.20pre10)on the Mac put together by Frank Schima (thank you Frank) and I noticed a problem that I thought I would pass along. This is under OS 10.9 Mavericks with the latest Xquartz (X11) installed. If one outputs a standard (in this case for Fe) file from Hephaestus and attempts to read it in as an "xmu" file in athena, the following happens. The element field is identified as Beryllium and E0 is set to 0. The data while looking fine during the input dialog looks fine. Changing the Element to Fe and specifying the K edge results and selecting a change in E0 (to tabulated value for example) results in the tabulated value popping up in the E0 box, however, plotting results in the same screen values returning Be L2 edge and a value of 0 for E0. Note the strange values for the Pre-edge range as well (12106 to 6053 eV). Fixing this is of no use either as soon as one plots, the strange values return. I have tried reading the data in as both norm(E) and xmu (it is an xmu file) to no avail. Any suggestions as to what I might try next? Cheers, Paul p.s. there are attachments demonstrating the values, but if they get dropped the text description should suffice.

There is no such thing in Athena's column selection dialog as an "xmu" option. There is a "mu(E)" option and an "xmu.dat" option. The former is for XAS data with the expectation that it will betreated as EXAFS data (as opposed to the "xanes" option, which disables background removal for the data group). The latter is for the xmu.dat file that Feff writes out. That even made it into the document! http://bruceravel.github.io/demeter/aug/import/columns.html#datatypesandener...
