CORRECTIONS TO EQUATIONS FOR ESTIMATING THE COUNTING-STATISTICAL ERRORS IN DIFFRACTION STRESS MEASUREMENTS

摘要

Two corrections are made to the equations for estimating the counting statistical errors in diffraction stress measurements. It is shown that the previous equations provide a conservative estimate of the counting-statistical component of the random errors in stress measurements. The results from the corrected equations are compared to a Monte Carlo model and to replicated measurements. A procedure to handle other sources of random error is also suggested. [References: 7]
