Updated User's Guide for Sammy: Multilevel R-Matrix Fits to Neutron Data Using Bayes' Equations

“…These approximations have the advantage that the calculation occurs more rapidly because fewer computations are required; however, they also have the disadvantage that unphysical cross sections may be generated. Use of these options is discouraged for new analyses; the options are included within SAMMY for the sake of completeness, to permit use of SAMMY with most ENDF resonance parameter information, and to facilitate comparisons with older codes such as SIOB [GD78].…”
