urn:nasa:pds:a15xrfs_surface_xray_counts 1.0 1.24.0.0 Product_Bundle 2025 10.17189/hwhm-x119 This volume contains two tables of time-ordered, event count rates acquired by the Apollo 15 X-Ray Fluorescence Spectrometer from 30 July to 04 August 1971 during lunar orbit. The tables include counts for all channels of the three proportional counters (unfiltered, magnesium filter, aluminum filter) and the solar monitor. David R.
