Thanks for your workaround. This really works!

Despite this i still have strange results, if i keep R and delta as variables. Here i have lots of arcsin terms that do not really contribute to the integral. If i assume delta>=0, R>=0 and theta::real. But maybe i misunderstood the results.

Nevertheless thanks for your help!
