Dear all, I am a new user of Athena and encountered some issues with data plotting. While plotting the uXAS data for Fe K pre-edge the quality of plotting is somehow less sharp compared to the actual data I plotted using other graphical tool (see below) [cid:4465cab9-2ae8-49e7-8253-e54ac3d22bb7] vs what I get from Athena [cid:4db817c1-78d0-4ac8-b094-12d37d055466] As you can see the resolution of the pre-edge in Athena is so poor I cannot resolve the Fe2+/Fe3+ ratio as the peak for Fe3+ is not visible. (I plotted Bruce's data from lepidocrocite to see if it's a common problem and it seems that his data look much better than mine). During my time on synchrotron we actually spent a lot of time to resolve best resolution on the pre edge, so it's not a acquisition problem. Does anyone have any idea how to fix this? I am attaching the project file and txt file (plot FluoRT2 column) with the original data. Thank you for your help, Weronika Ofierska
