Thanks. I think I have a clue now about my main topic after all this
e-mail. However I put on a question about spotread.
When I read the F5 patch row with spotread afterwards. I got this results



                X       Y               Z

Printread 35.186        18.810  1.2915

Spotread  34.793552 18.543380    1.277729



Can someone explain the differences here? I have been confused about
this for a while. The results above are without fwa compensation.

And for the reference I made my target without the -c option.
