The maximum number of polynomial coefficients to be allowed for the duration of this reduction.
For POLY trace fits, the order of the polynomials used for each fit may be varied up to this limit, but may not be set to higher values.
For SPLINE trace fits this is the maximum number of fit parameters which can be used. A high vale may be needed. The number of parameters required is (knots+7)*2.
The default value is 32, which should be acceptable in most cases.
