Apollo 15 and 16 X-Ray Fluorescence Spectrometers - Energy Channels and Field of View/Surface Resolution Discrepancies 2016-06-24 This report identifies known discrepancies in the literature regarding two characteristics of the Apollo 15 and Apollo 16 X-Ray Fluorescense Spectrometers: (a) the overall energy range and the individual channels and (b) the field of view and surface resolution. Dr. David Williams, NASA Goddard Space Flight Center, provided this report in 2016.
