Re: question about background rates in BCAL

Dear Alex,
I just looked and there are no rate plots in the FCal section either, you
of course discuss there the radiation damage, but this is slightly
different as it is real measurements.
This EM background rates come form the MC, so I would think they should
more go into the simulation section, but of course the individual calo
sections are also fine.
cheers elke
