evaluateWithNan

public double evaluateWithNan(VectorG azcosz)

The dimension of the parameter vector must match our lm-tupel. Each index in the lm-tupel links to a zonal spherical harmonics U_l,m that is evaluated at the specified azimuth and cos(90-h). The model value is the sum of all harmonics, multiplied by their relevant parameter weights. The argument is the azimuth in the first index and the
