Dear Claus,
the ZDC sees between 1 and 40 neutrons per event. To accomadate this
range we split the signal and attenuate one path. This path then goes to
what we call the low gain ADC while the unattenuated signal is what is
currently returned by the RDO module. Andrei Makeev has a modified version
of the rdo module that also creates low gain values but he had some
problems with BRAT2. I will talk with him about it today.
Yours Michael
