Summary of the progression of systematic corrections and the associated standard error after each correction, for 10 K. (a) Ratio of raw counts of upstream and downstream ion chambers with standard error derived from repeated measurements. (b) Ratio of ion chambers after correction for dark current. (c) [μ/ρ][ρt] from taking the logarithm of (b). (d) Converting to units of the mass attenuation coefficients and correcting for scattering, according to equation (14). (e) Corrected measurements with roughness correction and corresponding uncertainty. |
