Keyword:XSTHRESHOLD
From FISPACT-II Wiki
XSTHRESHOLD xs_thresh {1.0E-12}
This keyword specifies minimum cross section for inclusion within the pathways-based uncertainty analysis. The default is 1.0E-12 barns but this can be set at other values to reduce the computational expense of a simulation (for other options see UNCERTAINTY) or to probe small cross sections. A value of 0 forces all cross sections to be used.
