=== fun (function definition)<span id="fun"></span> ===

 '''fun''' ''NAME'' ''TYPE'' [ ... ]

Defines a function that can be used with detector responses. Input values:

{|
|<tt>''NAME''</tt>
|: function name
|-
|<tt>''TYPE''</tt>
|: function type
|}

The remaining input values are type-dependent.

<u>Notes:</u>
* The defined function is linked to detector response using [[ENDF reaction MT's and macroscopic reaction numbers|MT -100 ]] (syntax: dr -100 ''NAME'').
* The defined function currently is only supported as a flux-based function, aka, flux multiplier.

The available function types are:
::{| class="wikitable" style="text-align: left;"
! Type
! Description
|-
| [[#fun_1|<tt>1</tt>]]
| point-wise tabular data
|-
|}

The syntax for the available types is as follows:

 '''fun''' ''NAME'' '''1''' ''INTT'' ''X<sub>1</sub>'' ''F<sub>1</sub>'' ''X<sub>2</sub>'' ''F<sub>2</sub>'' ... <span id="fun_1"></span>

{|
|<tt>''INTT''</tt>
|: is the interpolation type (1 = histogram, 2 = lin-lin, 3 = lin-log, 4 = log-lin, 5 = log-log)
|-
|<tt>''X<sub>i</sub>'', ''F<sub>i</sub>''</tt>
|: are the tabulated variable-value pairs
|}
