Hello,

I simulated photons in a momentum range [100 MeV, 1 GeV] using the fast simulation,
with Box Generator.
I simulated 1000 events and I reconstructed only 241 photons.
If I look to the theta distribution of the photons there is an hole
between 20° and 140°.

I attach the simfast.C and the theta distribution figure.
The pandaroot version is 24621.

Any idea?

Thanks in advance
Elisa

Hi Elisa,

There is a bug fix in scrut14 and the trunk for the EMC barrel. Klaus fixed it some time ago but somehow it wasn't in the svn.

Cheers
Ralf
