When Polynomial extraction gives wrong results, a new algorithm has been developed in order to compute background. It uses 2-D surface splines interpolation, which is more adaptable. In consequence it is very important to play iteratively with parameters in order to check the background model | When Polynomial extraction gives wrong results, a new algorithm has been developed in order to compute background.
