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 2x(knots+7).
The default value is 50, which should be acceptable in most cases.
