5Description::
6This control allows the user to specify the number of basis functions to be
7used in the random field representation (e.g. either a Karhunen-Loeve or Principal Components expansion).
8Typically, a small number of basis functions (3-5) will be sufficient to represent a significant
9amount of the variance in the response field.  However, this depends on the particulars of the problem.
10THIS IS AN EXPERIMENTAL CAPABILITY UNDER ACTIVE DEVELOPMENT.

12<b> Default Behavior </b>
13If the user specifies neither \c trunction_tolerance nor \c expansion_bases, then
14the number of expansion bases that captures 95% of the variance will be used.
