Installing and using the xrfdisplay_epics application

While the Epics display screens give access to the low-level Epics interface for the Xspress3 driver, most Xspress3 users will use the interface for X-ray Fluoresence (XRF) spectroscopy. The Epics display screens do not give a very rich or high-level interface for working with the XRF spectra. The Epics XRF Control application from xraylarch can be used for basic interactions with detectors using the Xspress3 module, and a richer set of tools for working with XRF spectra.

By default this will be installed with the build_xpsress3.py script discussed in Installation, downloading and installing a Anaconda Python environment in /home/xspress3/xraylarch, which includes a program called xrfdisplay_epics that will display XRF spectra.
