Hi Donghee,

It's actually a question I do not have an answer, to include all the other subdetectors or not when calculationg error matrices.
Other subdetectors can cause a preshower with some probablility and photons reconstructed after preshower will have worse resolution, even if they are reconstructed at all.
And I do not know if to include them in error matrix calculation or not.

But I do not have strong arguments against it, so you can use the whole PANDA for error matrix calculation if you want.

Dima
