Hi,
It's pity that it does not help, i.e. usage of emc_error_matrix_1.root instead of emc_error_matrix_default.root.
Comment to Stefano, that emc_error_matrix_1.root was calculated for geometry which is different from current only for forward endcap and modification in reconstruction code should not be (?) relevant for this case.
Comment to Donghee
> It means that in fast simulation the error matrix "emc_error_matrix_1.root" has been accessed correclty but in full simulation old parameterization emc_error_matrix_default.root was used up to now.
No, in fast simuilation the error matrices were calculated/parametrized independently.
> Did you make parametrizations for Barrel, Forward endcap, Backward endcap, forward EMC, all 4 parts separately?
There is a separate parametrization for each EMC part but I calculated them in one macro.
But the conclusion is that error matrices should be recalculated at least for modified forward endcap, but parametrization/fit should be checked anyway, since I do not suppose that only forward endcap introduces problems.
So it makes sense to start with some QA macro to look for pull distribution for pi0 before/after 4Cfit and only later to recalculate error matrices.
