1-11 (²11)

Selection criteria (0=MAT, 1=ZA) (DEFault = 0)

12-22 (E11.4)

Minimum cross section of interest (barns).
0.0 or less - the program will use 1.0e-10 barn (DEF).

23-33 (I11)

Treatment of reactions for which background cross section is not given.
= 0 – ignor (i.e. no output) (DEF).
= 1 – output resonance contribution.

34-44 (²11)

Operating mode
= 0 – calculate. Minimum output listing (DEF).
= 1 – calculate. List all resonance parameters.
= 2 – EDIT mode. No calculation.

45-55 (²11)

Negative cross section treatment
= 0 – O.K. – No change.
= 1 – Set = 0.

56-66 (²11)

Monitor mode selection
= 0 – Normal operation (DEF).
= 1 – Monitor progress of reconstruction of file 2 data and combining file 2 and file 3 data.

1-60 (À60)

ENDF/B input data filename (DEF option ENDFB.IN)

3

1-60 (À60)

ENDF/B output data filename (DEF option ENDFB.OUT )

4-N

1 -11 (²11)

Minimum
MAT or ZA
(see 1-11, line 1)

Up to 100 MAT or ZA ranges may be specified, one range per line.
The list is terminated by a BLANK line.

If the the UPPER limit of any request is less than the LOWER limit, the UPPER limit will be set equal to the LOWER limit.

If the first request line is BLANK it will terminate the request list and cause all data to be retrieved.

The lower and upper ENERGY limits must be ZERO, or BLANK (DEF), unless you wish to only process a portion of resonance regions.

These energy limits are only read from the first MAT/ZA request line.

If both are ZERO (or BLANK) the entire resonance region for each material will be processed.

12 -22 (²11)

Maximum
MAT or ZA
(see 1-11, line 1)

23-33 (E11.4)

Lower ENERGY limit for processing

34-44 (E11.4)

Upper ENERGY limit for processing

Ê

1-11 (E11.4)

Energy for ERROR law

If the error law is energy independent only a single error is given (DEFault 0.001)

If the error law is energy dependent up to 20 energies, error pairs are allowed. For an energy dependent error law all energies must be ascending energy order.

The end of error law is terminated by a BLANK line.

12-22 (E11.4)

Allowable fractional error for error law

   Let RESULT.1 is the ENDF formatted file after processing by the LINEAR code.
Assuming that we intend to calculate within an accuracy of 1 per-cent 
(0.01 as a fraction) all neutron cross sections for included materials. Let name of
output ENDF formatted file will be RESULT.2.


The asterisks in this example, following below, in input file have to
correspond to the blanks. Here they are presented to facilitate the
calculation of positions.
