AUTHORS MESSAGE Spectra
--------------- Spectra
THE REPORT DESCRIBED ABOVE IS THE LATEST PUBLISHED DOCUMENTATION Spectra
FOR THIS PROGRAM. HOWEVER, THE COMMENTS BELOW SHOULD BE CONSIDERED Spectra
THE LATEST DOCUMENTATION INCLUDING ALL RECENT IMPROVEMENTS. PLEASE Spectra
READ ALL OF THESE COMMENTS BEFORE IMPLEMENTATION. Spectra
Spectra
AT THE PRESENT TIME WE ARE ATTEMPTING TO DEVELOP A SET OF COMPUTER Spectra
INDEPENDENT PROGRAMS THAT CAN EASILY BE IMPLEMENTED ON ANY ONE Spectra
OF A WIDE VARIETY OF COMPUTERS. IN ORDER TO ASSIST IN THIS PROJECT Spectra
IT WOULD BE APPECIATED IF YOU WOULD NOTIFY THE AUTHOR OF ANY Spectra
COMPILER DIAGNOSTICS, OPERATING PROBLEMS OR SUGGESTIONS ON HOW TO Spectra
IMPROVE THIS PROGRAM. HOPEFULLY, IN THIS WAY FUTURE VERSIONS OF Spectra
THIS PROGRAM WILL BE COMPLETELY COMPATIBLE FOR USE ON YOUR Spectra
COMPUTER. Spectra
Spectra
PURPOSE Spectra
------- Spectra
THIS PROGRAM IS DESIGNED TO CONVERT ENDF/B FILE 3, 23 AND 27 DATA Spectra
TO LINEAR-LINEAR INTERPOLABLE FORM. ANY SECTION THAT IS ALREADY Spectra
LINEAR-LINEAR INTERPOLABLE WILL BE THINNED. Spectra
Spectra
IN THE FOLLOWING DISCUSSION FOR SIMPLICITY THE ENDF/B TERMINOLOGY Spectra
---ENDF/B TAPE---WILL BE USED. IN FACT THE ACTUAL MEDIUM MAY BE Spectra
TAPE, CARDS, DISK OR ANY OTHER MEDIUM. Spectra
Spectra
ENDF/B FORMAT Spectra
------------- Spectra
THIS PROGRAM ONLY USES THE ENDF/B BCD OR CARD IMAGE FORMAT (AS Spectra
OPPOSED TO THE BINARY FORMAT) AND CAN HANDLE DATA IN ANY VERSION Spectra
OF THE ENDF/B FORMAT (I.E., ENDF/B-I, II,III, IV, V OR VI FORMAT). Spectra
Spectra
IT IS ASSUMED THAT THE DATA IS CORRECTLY CODED IN THE ENDF/B Spectra
FORMAT AND NO ERROR CHECKING IS PERFORMED. IN PARTICULAR IT IS Spectra
ASSUMED THAT THE MAT, MF AND MT ON EACH LINE IS CORRECT. SEQUENCE Spectra
NUMBERS (COLUMNS 76-80) ARE IGNORED ON INPUT, BUT WILL BE Spectra
CORRECTLY OUTPUT ON ALL LINES. THE FORMAT OF SECTION MF=1, MT=451 Spectra
AND ALL SECTIONS OF MF=3 MUST BE CORRECT. THE PROGRAM COPIES ALL Spectra
OTHER SECTION OF DATA AS HOLLERITH AND AS SUCH IS INSENSITIVE TO Spectra
THE CORRECTNESS OR INCORRECTNESS OF ALL OTHER SECTIONS. Spectra
Spectra
OUTPUT FORMAT Spectra
------------- Spectra
IN THIS VERSION OF LINEAR ALL ENERGIES WILL BE OUTPUT IN Spectra
F (INSTEAD OF E) FORMAT IN ORDER TO ALLOW ENERGIES TO BE WRITTEN Spectra
WITH UP TO 9 DIGITS OF ACCURACY. IN PREVIOUS VERSIONS THIS WAS AN Spectra
OUTPUT OPTION. HOWEVER USE OF THIS OPTION TO COMPARE THE RESULTS Spectra
OF ENERGIES WRITTEN IN THE NORMAL ENDF/B CONVENTION OF 6 DIGITS Spectra
TO THE 9 DIGIT OUTPUT FROM THIS PROGRAM DEMONSTRATED THAT FAILURE Spectra
TO USE THE 9 DIGIT OUTPUT CAN LEAD TO LARGE ERRORS IN THE DATA Spectra
DUE TO TRUNCATION OF ENERGIES TO 6 DIGITS DURING OUTPUT. Spectra
Spectra
CONTENTS OF OUTPUT Spectra
------------------ Spectra
ENTIRE EVALUATIONS ARE OUTPUT, NOT JUST THE LINEARIZED DATA Spectra
CROSS SECTIONS, E.G. ANGULAR AND ENERGY DISTRIBUTIONS ARE ALSO Spectra
INCLUDED. Spectra
Spectra
DOCUMENTATION Spectra
------------- Spectra
THE FACT THAT THIS PROGRAM HAS OPERATED ON THE DATA IS DOCUMENTED Spectra
BY THE ADDITION OF 3 COMMENT LINES AT THE END OF EACH HOLLERITH Spectra
SECTION IN THE FORM Spectra
Spectra
***************** PROGRAM SPECTRA (2018-1) **************** Spectra
FOR ALL DATA GREATER THAN 1.00000-10 IN ABSOLUTE VALUE Spectra
DATA LINEARIZED TO WITHIN AN ACCURACY OF 0.1 PER-CENT Spectra
Spectra
THE ORDER OF SIMILAR COMMENTS (FROM RECENT, SIGMA1 AND GROUPIE) Spectra
REPRESENTS A COMPLETE HISTORY OF ALL OPERATIONS PERFORMED ON Spectra
THE DATA BY THESE PROGRAMS. Spectra
Spectra
THESE COMMENT LINES ARE ONLY ADDED TO EXISTING HOLLERITH SECTIONS, Spectra
I.E., THIS PROGRAM WILL NOT CREATE A HOLLERITH SECTION. THE FORMAT Spectra
OF THE HOLLERITH SECTION IN ENDF/B-V DIFFERS FROM THE THAT OF Spectra
EARLIER VERSIONS OF ENDF/B. BY READING AN EXISTING MF=1, MT=451 Spectra
IT IS POSSIBLE FOR THIS PROGRAM TO DETERMINE WHICH VERSION OF Spectra
THE ENDF/B FORMAT THE DATA IS IN. WITHOUT HAVING A SECTION OF Spectra
MF=1, MT=451 PRESENT IT IS IMPOSSIBLE FOR THIS PROGRAM TO Spectra
DETERMINE WHICH VERSION OF THE ENDF/B FORMAT THE DATA IS IN, AND Spectra
AS SUCH IT IS IMPOSSIBLE FOR THE PROGRAM TO DETERMINE WHAT FORMAT Spectra
SHOULD BE USED TO CREATE A HOLLERITH SECTION. Spectra
Spectra
REACTION INDEX Spectra
-------------- Spectra
THIS PROGRAM DOES NOT USE THE REACTION INDEX WHICH IS GIVEN IN Spectra
SECTION MF=1, MT=451 OF EACH EVALUATION. Spectra
Spectra
THIS PROGRAM DOES NOT UPDATE THE REACTION INDEX IN MF=1, MT=451. Spectra
THIS CONVENTION HAS BEEN ADOPTED BECAUSE MOST USERS DO NOT Spectra
REQUIRE A CORRECT REACTION INDEX FOR THEIR APPLICATIONS AND IT WAS Spectra
NOT CONSIDERED WORTHWHILE TO INCLUDE THE OVERHEAD OF CONSTRUCTING Spectra
A CORRECT REACTION INDEX IN THIS PROGRAM. HOWEVER, IF YOU REQUIRE Spectra
A REACTION INDEX FOR YOUR APPLICATIONS, AFTER RUNNING THIS PROGRAM Spectra
YOU MAY USE PROGRAM DICTIN TO CREATE A CORRECT REACTION INDEX. Spectra
Spectra
SECTION SIZE Spectra
------------ Spectra
SINCE THIS PROGRAM USES A LOGICAL PAGING SYSTEM THERE IS NO LIMIT Spectra
TO THE NUMBER OF POINTS IN ANY SECTION, E.G., THE TOTAL CROSS Spectra
SECTION MAY BE REPRESENTED BY 200,000 DATA POINTS. Spectra
Spectra
FOR ANY LINEARIZED SECTION THAT CONTAINS 60000 OR FEWER POINTS Spectra
THE ENTIRE OPERATION WILL BE PERFORMED IN CORE AND THE LINEARIZED Spectra
DATA WILL BE OUTPUT DIRECTLY TO THE ENDF/B FORMAT. FOR ANY SECTION Spectra
THAT CONTAINS MORE POINTS THE DATA WILL BE LINEARIZED A PAGE AT A Spectra
TIME (1 PAGE = 60000 POINTS) AND OUTPUT TO SCRATCH. AFTER THE Spectra
ENTIRE SECTION HAS BEEN LINEARIZED THE DATA WILL BE READ BACK FROM Spectra
SCRATCH AND OUTPUT TO THE ENDF/B FORMAT. Spectra
Spectra
SELECTION OF DATA Spectra
----------------- Spectra
THE PROGRAM SELECTS DATA TO BE LINEARIZED BASED EITHER ON EITHER Spectra
MAT (ENDF/B MAT NO.) OR ZA AS WELL AS MF AND MT NUMBERS. THIS Spectra
PROGRAM ALLOWS UP TO 100 MAT/MF/MT OR ZA/MF/MT RANGES TO BE Spectra
SPECIFIED BY INPUT PARAMETERS. THE PROGRAM WILL ASSUME THAT THE Spectra
ENDF/B TAPE IS IN MAT ORDER, REGARDLESS OF THE CRITERIA USED Spectra
TO RETRIEVE MATERIALS. IF RETRIEVAL IS BY MAT RANGE THE PROGRAM Spectra
WILL TERMINATE WHEN A MAT IS FOUND THAT IS ABOVE ALL REQUESTED Spectra
MAT RANGES. IF RETRIEVAL IS BY ZA RANGE THE PROGRAM WILL SEARCH Spectra
THE ENTIRE ENDF/B TAPE. Spectra
Spectra
PROGRAM OPERATION Spectra
----------------- Spectra
EACH SECTION OF DATA IS CONSIDERED SEPARATELY. EACH SECTION OF Spectra
ENDF/B DATA TO LINEARIZE IS REPRESENTED BY A TABLE OF ENERGY Spectra
VS. CROSS SECTION AND ANY ONE OF FIVE ALLOWABLE INTERPOLATION LAWS Spectra
BETWEEN ANY TWO TABULATED POINTS. THIS PROGRAM WILL REPLACE EACH Spectra
SECTION OF DATA CROSS SECTIONS BY A NEW TABLE OF ENERGY VS. Spectra
CROSS SECTION IN WHICH THE INTERPOLATION LAW IS ALWAYS LINEAR IN Spectra
ENERGY AND CROSS SECTION BETWEEN ANY TWO TABULATED POINTS. Spectra
Spectra
DATA IS READ AND LINEARIZED A PAGE AT A TIME (ONE PAGE CONTAINS Spectra
60000 DATA POINTS). IF THE FINAL LINEARIZED SECTION CONTAINS TWO Spectra
PAGES OR LESS, DATA POINTS IT WILL BE ENTIRELY CORE RESIDENT Spectra
AFTER IT HAS BEEN LINEARIZED AND WILL BE WRITTEN DIRECTLY FROM Spectra
CORE TO THE OUTPUT TAPE. IF THE LINEARIZED SECTION IS LARGER THAN Spectra
TWO PAGES, AFTER EACH PAGE IS LINEARIZED IT WILL BE WRITTEN TO Spectra
SCRATCH. AFTER THE ENTIRE SECTION HAS BEEN LINEARIZED IT WILL Spectra
BE READ BACK FROM SCRATCH, TWO PAGES AT A TIME, AND WRITTEN TO Spectra
THE OUTPUT TAPE. Spectra
Spectra
KEEP EVALUATED DATA POINTS Spectra
-------------------------- Spectra
SOMETIMES IT IS CONVENIENT TO KEEP ALL ENERGY POINTS WHICH WERE Spectra
PRESENT IN THE ORIGINAL EVALUATION AND TO MERELY SUPPLEMENT THESE Spectra
POINTS WITH ADDITIONAL ENERGY POINTS IN ORDER TO LINEARIZE THE Spectra
CROSS SECTIONS. FOR EXAMPLE, IT IS OFTEN CONVENIENT TO KEEP THE Spectra
THERMAL VALUE (AT 0.0253 EV) OR THE VALUE AT 14.1 MEV. Spectra
Spectra
THE CURRENT VERSION OF THIS PROGRAM WILL ALLOW THE USER TO KEEP Spectra
ALL ORIGINAL EVALUATED DATA POINTS BY SPECIFYING 1 IN COLUMNS Spectra
34-44 OF THE FIRST INPUT LINE. THIS WILL TURN OFF THE BACKWARD Spectra
THINNING (SEE UCRL-50400, VOL. 17, PART A FOR EXPLANATION) AND Spectra
RESULT IN ALL ORIGINAL ENERGY POINTS BEING KEPT. CAUTION SHOULD Spectra
BE EXERCISED IN USING THIS OPTION SINCE IT CAN RESULT IN A Spectra
CONSIDERABLE INCREASE IN THE NUMBER OF DATA POINTS OUTPUT BY Spectra
THIS CODE. Spectra
Spectra
FOR ALL USERS WHO ARE NOT INTERESTED IN THIS OPTIONS NO CHANGES Spectra
ARE REQUIRED IN THE INPUT TO THIS PROGRAM, I. E. IF COLUMNS Spectra
34-44 ARE BLANK (AS FOR ALL PREVIOUS VERSIONS OF THIS CODE) THE Spectra
PROGRAM WILL OPERATE EXACTLY AS IT DID BEFORE. Spectra
Spectra
ALLOWABLE ERROR Spectra
--------------- Spectra
ALLOWABLE ERROR MUST ALWAYS BE SPECIFIED IN THE INPUT TO THIS Spectra
PROGRAM AS A FRACTION, NOT A PER-CENT. FOR EXAMPLE, INPUT THE Spectra
ALLOWABLE FRACTIONAL ERROR 0.001 IN ORDER TO OBTAIN DATA THAT IS Spectra
ACCURATE TO WITHIN 0.1 PER-CENT. Spectra
Spectra
THE CONVERSION OF THE DATA FROM THE GENERAL INTERPOLATION FORM TO Spectra
LINARLY INTERPOLABLE FORM CANNOT BE PERFORMED EXACTLY. HOWEVER, IT Spectra
CAN BE PERFORMED TO VIRTUALLY ANY REQUIRED ACCURACY AND MOST Spectra
IMPORTANTLY CAN BE PERFORMED TO A TOLERANCE THAT IS SMALL COMPARED Spectra
TO THE UNCERTAINTY IN THE CROSS SECTIONS THEMSELVES. AS SUCH THE Spectra
CONVERSION OF CROSS SECTIONS TO LINEARLY INTERPOLABLE FORM CAN BE Spectra
PERFORMED WITH ESSENTIALLY NO LOSE OF INFORMATION. Spectra
Spectra
THE ALLOWABLE ERROR MAY BE ENERGY INDEPENDENT (CONSTANT) OR ENERGY Spectra
DEPENDENT. THE ALLOWABLE ERROR IS DESCRIBED BY A TABULATED Spectra
FUNCTION OF UP TO 20 (ENERGY,ERROR) PAIRS AND LINEAR INTERPOLATION Spectra
BETWEEN TABULATED POINTS. IF ONLY ONE TABULATED POINT IS GIVEN THE Spectra
ERROR WILL BE CONSIDERED CONSTANT OVER THE ENTIRE ENERGY RANGE. Spectra
WITH THIS ENERGY DEPENDENT ERROR ONE MAY OPTIMIZE THE OUTPUT FOR Spectra
ANY GIVEN APPLICATION BY USING A SMALL ERROR IN THE ENERGY RANGE Spectra
OF INTEREST AND A LESS STRINGENT ERROR IN OTHER ENERGY RANGES. Spectra
Spectra
DEFAULT ALLOWABLE ERROR Spectra
----------------------- Spectra
IN ORDER TO INSURE CONVERGENCE OF THE LINEARIZING ALGORITHM THE Spectra
ALLOWABLE ERROR MUST BE POSITIVE. IF THE USER INPUTS AN ERROR Spectra
THAT IS NOT POSITIVE IT WILL AUTOMATICALLY BE SET TO THE DEFAULT Spectra
VALUE (CURRENTLY 0.001, CORRESPONDING TO 0.1 PER-CENT) AND Spectra
INDICATED AS SUCH IN THE OUTPUT LISTING. Spectra
Spectra
COULOMB PENETRABILITY (INTERPOLATION LAW = 6) Spectra
-------------------------------------------- Spectra
INTRODUCED FOR ENDF/B-VI. THIS IS DEFINED AS, Spectra
Spectra
SIG(E) = C1*EXP(-C2/SQRT(E - T)) Spectra
Spectra
THIS PROGRAM ONLY CONSIDERS EXOTHERMIC REACTIONS - T = 0 Spectra
Spectra
SIG(E) = C1*EXP(-C2/SQRT(E)) Spectra
Spectra
WARNING...THIS INTERPOLATION LAW SHOULD ONLY BE USED FOR REACTIONS Spectra
WHICH HAVE A POSITIVE Q-VALUE (EXOTHERMIC REACTIONS), Spectra
SINCE HERE WE ONLY CONSIDER T = 0.0 IN THE FORMALISM. Spectra
IN ALL OTHER CASES A WARNING MESSAGE WILL BE PRINTED. Spectra

INPUT PARAMETERS Spectra
---------------- Spectra
FOR VERSIONS EARLIER THAN 90-1 THIS PROGRAM ONLY ALLOWED THE USER Spectra
TO SPECIFY BY INPUT PARAMETERS WHICH MATERIALS (MAT) TO PROCESS. Spectra
FOR EACH REQUESTED MATERIAL NEUTRON INTERACTION CROSS SECTIONS Spectra
(MF=3) WOULD BE LINEARIZED AND THE REMAINDER OF THE MATERIAL Spectra
WOULD BE COPIED. Spectra
Spectra
FOR VERSIONS 90-1 AND LATER THIS PROGRAM WILL ALLOW THE USER TO Spectra
TO SPECIFY BY INPUT PARAMETERS EXACTLY WHAT SECTIONS OF DATA Spectra
TO PROCESS. FOR EACH SECTION OF DATA, SPECIFIED BY MAT, MF, MT Spectra
RANGES, SECTIONS OF MF=3, 23 AND 27 WILL BE LINEARIZED AND ALL Spectra
OTHER REQUESTED SECTIONS WILL BE COPIED. ALL SECTIONS WHICH ARE Spectra
NOT EXPLICITLY REQUESTED WILL BE SKIPPED AND WILL NOT APPEAR ON Spectra
ENDF/B FILE OUTPUT BY THIS PROGRAM. Spectra
Spectra
WITH THIS NEW PROCEDURE YOU CAN MINIMIZE THE SIZE OF THE ENDF/B Spectra
FILE OUTPUT BY THIS PROGRAM, E.G., IF YOU ONLY WANT NEUTRON Spectra
CROSS SECTIONS FOR SUBSEQUENT PROCESSING YOU NEED ONLY REQUEST Spectra
ONLY MF=3 DATA. Spectra
Spectra
HOWEVER, YOU MUST UNDERSTAND THAT ONLY THOSE SECTIONS WHICH YOU Spectra
EXPLICITLY REQUEST WILL APPEAR ON THE ENDF/B FILE OUTPUT BY Spectra
THIS PROGRAM. FOR EXAMPLE, IF YOU WISH TO DOCUMENT EXACTLY Spectra
HOW YOU LINEARIZED THE DATA BY INCLUDING COMMENTS IN MF=1, MT=451 Spectra
THEN YOU MUST EXPLICITLY REQUEST THAT MF=1, MT=451 BE PROCESSED Spectra
FOR EACH MATERIAL THAT YOU REQUEST. SIMILAR IF YOU WANT THE Spectra
ENTIRE EVALUATION YOU MUST REQUEST ALL MF AND MT TO BE OUTPUT. Spectra

THE SCRATCH FILE PRINT OUT THE TOTAL NUMBER OF Spectra
POINTS ON SCRATCH AND THE LOWER AND UPPER Spectra
ENERGY LIMITS OF THE PAGE (THIS OPTION MAY BE Spectra
USED IN ORDER TO MONITOR THE EXECUTION SPEED Spectra
OF LONG RUNNING JOBS). Spectra
23-33 MINIMUM CROSS SECTION OF INTEREST (BARNS). Spectra
(IF 0.0 OR LESS IS INPUT THE PROGRAM WILL Spectra
USE 1.0E-10). ENERGY INTERVALS WILL NOT BE Spectra
SUB-DIVIDED IF THE ABSOLUTE VALUE OF THE CROSS Spectra
SECTION WITHIN THE INTERVAL IS LESS THAN THIS VALUE. Spectra
AN EXCEPTION TO THIS RULE IS NEAR THRESHOLDS ENERGY Spectra
INTERVALS WILL BE SUB-DIVIDED UNTIL CONVERGENCE Spectra
REGARDLESS OF THE MAGNITUDE OF THE CROSS SECTION. Spectra
34-44 KEEP ORIGINAL EVALUATED DATA POINTS. Spectra

20-22 UPPER MT LIMIT Spectra
UP TO 100 RANGES MAY BE SPECIFIED, ONLY ONE RANGE Spectra
PER LINE. THE LIST OF RANGES IS TERMINATED BY A Spectra
BLANK LINE. IF THE UPPER MAT LIMIT OF ANY REQUEST Spectra
IS LESS THAN THE LOW LIMIT IT WILL BE SET EQUAL TO Spectra
THE LOWER LIMIT. IF THE UPPER LIMIT IS STILL ZERO Spectra
IT WILL BE SET EQUAL TO 999999. IF THE UPPER MF OR Spectra
MT LIMIT IS ZERO IT WILL BE SET TO 99 OR 999 Spectra
RESPECTIVELY. Spectra
VARY 1-11 ENERGY FOR ERROR LAW Spectra
12-22 ALLOWABLE FRACTIONAL ERROR FOR ERROR LAW. Spectra
THE ACCEPTABLE LINEARIZING ERROR MAY BE SPECIFIED TO Spectra
BE EITHER ENERGY INDEPENDENT (DEFINED BY A SINGLE Spectra
ERROR), OR ENERGY DEPENDENT (DEFINED BY UP TO 20 Spectra
ENERGY, ERROR PAIRS). FOR THE ENERGY DEPENDENT CASE Spectra
LINEAR INTERPOLATION WILL BE USED TO DEFINE THE ERROR Spectra
AT ENERGIES BETWEEN THOSE AT WHICH IT IS TABULATED. Spectra
IN ALL CASES THE ERROR LAW IS TERMINATED BY A BLANK Spectra
LINE. IF ONLY ONE ENERGY, ERROR PAIR IS GIVEN THE Spectra
THE LAW WILL BE CONSIDERED TO BE ENERGY INDEPENDENT. Spectra
IF MORE THAN ONE PAIR IS GIVEN IT WILL BE CONSIDERED Spectra
TO BE ENERGY DEPENDENT (NOTE, ENERGY INDEPENDENT Spectra
FORM WILL RUN FASTER THAN THE EQUIVALENT ENERGY Spectra
DEPENDENT FORM). FOR AN ENERGY DEPENDENT ERROR LAW Spectra
ALL ENERGIES MUST BE ASCENDING ENERGY ORDER. FOR Spectra
CONVERGENCE OF THE LINEARIZING ALGORITHM ALL ERRORS Spectra
MUST BE POSITIVE. IF AN ALLOWABLE ERROR IS NOT Spectra
POSITIVE IT WILL BE SET EQUAL TO THE STANDARD OPTION Spectra
(CURRENTLY 0.001, CORRESPONDING TO 0.1 PER-CENT). Spectra
IF THE FIRST ERROR LINE IS BLANK IT WILL TERMINATE Spectra
THE ERROR LAW AND THE ERROR WILL BE TREATED AS Spectra
