Dear all,
i did a simple test
(tell me if i am wrong)
i took the look up prespec table x,y,z and calculated the r distance
and as you see they look very much "theoretical" as they are all the same !
Then i took the table from Strachen Laser measuremnts at GSI,
and the cristal front face have different r, as ecpected from "real life".
(see list at end).
Frontface means if i understood correctly, front of cristal housing.
Written in the word document.

A second test i did now is to take serious the measured target position offset that wrote Strachen,...
and the 2plus state shows up better.

If this is true, that the measured positions are different from the tabled one, i think we have to reevaluate all lookuptable and we have a problem.
maybee a serious problem, if we continue using the old tables.
Who is able to take care of this problem ?
