Thank you very much Joerg, Yes I am aware of the data gaps which are mentioned when I try to obtain the data, but as you said there should be something more than that. I will try to download it again.
It is very usefull that the database is improved continusly for improving suspicius data :) keep up the good job guys.
I will work more on that the next few days and wll write back here the resutls.
thanks,
Theo
