3. DESCRIPTION OF PROBLEM OR FUNCTION

GLUCS is a package of programs  for simultaneous evaluation of reaction cross sections. Evaluations  of cross sections and covariances are used as input for incorporat-  ing correlated data sets, particularly ratios. These data are read from Evaluated Nuclear Data File (ENDF/B-V) formatted files.
Measured data sets, including ratios and absolute and relative cross section data, are read and combined with the input evaluations via the least-squares technique. The resulting output evaluations have not only updated cross sections and covariances, but also cross-section covariances. These output data are written into ENDF/B-V format.

4. METHOD OF SOLUTION

A generalized least-squre technique, Bayes' theorem, is employed for the evaluation.
