Account of correlations in determination of errors in evaluated data

Suggested is a method of estimating sigmasub(f)(sup(235)U), sigmasub(f)(sup(239)Pu), α(235U), α(239Pu) and their errors. The correlation coefficients of errors in various points of the estimated curves have been obtained. As an example, α(239Pu) is estimated. The estimated α(239Pu) values and their errors, obtained with and without account of correlations between partial measurement errors are tabulated. The errors of the estimated α(239Pu) value for various energy points are in strong correlation with each other
