Each RAD observation contains the following: (1) Instrument counters, (2) Neutral particle count histograms in detectors D and E, (3) LET count histograms, (4) Absorbed dose rate in detectors B and E, (5) High-cadence dose rate in B and E (16 rates per observation). <_Description>Source: Master/CDFglobalAttributes/TEXT Please acknowledge the RAD Principal Investigator Dr. Hassler of Southwest Research Institute Boulder. <_Acknowledgement>Source: Master/CDFglobalAttributes/Acknowledgement <_Rights> SPDX Creative Commons Zero v1.0 Universal https://spdx.org/licenses/CC0-1.0.html https://spdx.org/licenses/ https://link.springer.com/article/10.1007/s11214-012-9913-1 Hassler et al (2014) The RAD instrument is described in detail in <_Note>URL also in all.xml.
