3. DESCRIPTION OF PROGRAM OR FUNCTION

Compares the evaluated nuclear  cross section data (in ENDF/B-IV format) with experimental data (in  EXFOR format) e.g. compare all the data curves for 92-U-238 (N,2N) from ENDF/B-IV, ENDF/B-V, and EXFOR master files.
[ top ]
4. METHOD OF SOLUTION

Combines the cross section data in EXFOR and/or ENDF/B-IV format, and converts them to a uniform format for further  processing, especially for graphical comparison of curves.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

Input data files must be correctly coded in ENDF/B-IV format and/or EXFOR format. In  general they are retrieval results for the required data. In EXFOR data files every subentry includes cross section data and SUB 001 of the same entry. In evaluated data files the data of MF=1 and MF=3 must be included.

6. TYPICAL RUNNING TIME

10 seconds are required on IBM 3081; (5.6 seconds for X4ECS and 3.8 seconds for SELDATA) when running the test problems on VAX. Execution time depends on the size of the input data files.

7. UNUSUAL FEATURES OF THE PROGRAM

All cross sections in the input data files are converted to an energy-data table in standard form; DATA-ERR is not included.
[ top ]
8. RELATED AND AUXILIARY PROGRAMS

On IBM 3081, the output data tables of X4SECS can be used by the graphics package TELL-A-GRAF to display curves and to produce hard copies. Since the number of curves to be  processed by TELL-A-GRAF is restricted to 35, the maximum number of  energy points per curve is 5000. If the data table file exceeds this number, SELDATA must be used to selectively restrict the number of data tables and data points.
