File: ICEHCR.format Version: NSSDC 2/20/98 JFC ------------------------------------------------------------------------------- ISEE-3/ICE HIGH ENERGY COSMIC RAY COMPOSITION TABLES ---------------------------------------------------- Data Set Coverage (yyyy-mm-dd): 1978-08-12 to 1991-04-30 Experiment: High Energy Cosmic Ray Experiment Principal Investigator: Dr. Mark E. Wiedenbeck, NASA JPL Data Set Contact: Dr. Mark E. Wiedenbeck, NASA JPL Data Set Submission Date: 1993-04-12 Data Set Description: The ASCII files in this data set contain tabular summaries of cosmic ray elemental and isotopic composition in interplanetary space at 1 A.U. near Earth as measured by the high energy cosmic ray experiment on ISEE-3/ICE. These measurements cover the time interval from August 1978 to April 1981 and particle nuclei energies in the general range of 50 to 500 MeV/nucleon. The contents of the files are as follows: elemental abundance Ratios in file TABLE1.txt, isotopic fractions in TABLE2.txt, and isotopic abundance ratios in TABLE3.txt. Each file also lists the references in which the measured values were published.
