Hi Nigel, Steve, Orestis, Tomas and Daniel, many, many thanks for all your effort and helpfull comments. I have testet the codes from Daniel and Tomas on our datasets and it is a perfect agreement between the results. Why not ? Mathematica is perfect if the code is perfect. And it is. I will test the other codes as soon as possible.
