Specifies the reject-threshold for object pixels.
Any pixels which deviate by more than TUNE_OBJRTHR sigma from the fitted polynomial model, will be clipped, and the model re-fitted. The polynomial model of the object profile is made by fitting a polynomial at each X-increment. These polynomials are then used to estimate the signal at each spatial sample of the object.
INITIAL SUGGESTED VALUE: 5.0.
