C021500100015 CORRECTION Corrected for: C021500100016 - elastic scattering events; C021500100017 - charged-particle reaction products; C021500100018 - nuclear reactions occuring not in target; C021500100019 - other (target thickness, finite beam spot size). C021500100020 ERR-ANALYS (DATA-ERR) Total uncertainty obtained by adding all C021500100021 errors in quadrature, and includes uncertainties due C021500100022 to statistical fluctuations in measurement of C021500100023 attenuation rates with target in and target out, as C021500100024 well as the error associated with determination of C021500100025 areal density of the target.
