Description

This ASCII file contains values and their uncertainties
for 25 abundance ratios of various pairs of chemical elements. The ratios
are based on 1978-1981 observations of ~50-500 MeV/n cosmic rays by the
U. Chicago cosmic ray experiment on ISEE 3. Each of the ratios is linked
in the ASCII file to the publication where its derivation is discussed.
