Description
Synchrotron radiation X-ray computed tomography (XCT) datasets were acquired at SPring-8 for a fine Bennu sample using multiple imaging conditions. This bundle includes two XCT image collections: absorption-contrast XCT acquired at 7.0 keV and phase-contrast XCT acquired at 8.0 keV. Instrument metadata documenting acquisition, reconstruction, and CT-value mapping parameters are provided for each dataset. The XCT imaging was performed on December 5, 2025.
