``<temperature_method>`` Element
--------------------------------
The ``<temperature_method>`` element has an accepted value of "nearest" or
"interpolation". A value of "nearest" indicates that for each cell, the nearest
temperature at which cross sections are given is to be applied, within a given
tolerance (see :ref:`temperature_tolerance`). A value of "multipole" indicates
that the windowed multipole method should be used to evaluate
temperature-dependent cross sections in the resolved resonance range (a
:ref:`windowed multipole library <multipole_library>` must also be available).
The ``<temperature_method>`` element has an accepted value of "nearest",

applied, within a given tolerance (see :ref:`temperature_tolerance`). A value of
"interpolation" indicates that cross sections are to be linear-linear
interpolated between temperatures at which nuclear data are present (see
