to be applied when the "nearest" temperature method is used. For example, if a

temperature in the range of 325 K to 355 K will be used to evaluate cross

sections. If the ``<temperature_method>`` is "interpolation", the tolerance
specified applies to cell temperatures outside of the data bounds. For example,
if a cell is specified at 695K, a tolerance of 15K and data is only available
at 700K and 1000K, the cell's cross sections will be evaluated at 700K, since
the desired temperature of 695K is within the tolerance of the actual data
despite not being bounded on both sides.
