[ Temperature ] section
==================================================

In this section, the free-gas thermal temperature is defined.
The unit is MeV.
Time dependence cannot be specified.
This temperature can also be defined as a cell parameter in the [cell] section; however, if regions overlap, the value defined in the [temperature] section takes precedence.
If the temperature is double defined, temperatures defined in this [temperature] sections are used.
If no definition, the default value :math:`2.585\times 10^{-8}\,\mathrm{MeV}` is used.
Note that in general temperature has an effect on only behavior of thermal neutrons, and has no effect on those of other particles.

The format is as follows.

.. code-block:: text

  [ Temperature ]
    reg                 tmp
    1                   1.0*1.e-8
    11                  5.0*1.e-8
    ( { 2 - 5 } 8 9 )   2.0*1.e-8
    ( 11 12 15 )        3.0*1.e-8
    16                  6.0*1.e-8
    ....                ........
    ....                ........

The format ( { 2 - 5 } 8 9 ) can be used.
However, any value that is not single numeric must be enclosed value by (  ) .
Lattice or universe specifications such as ( 6 < 10[1 0 0] < u=3 ) are not supported.

To change the order of region number (reg) and temperature (tmp), set as tmp reg.
The skip operator non can be used.
