[Primexd] Question

[Ilya Larin]

Hi Igal,
in the PrimEx simulations, we just add electronics noise first,
then cut the channel signal at our sparcification threshold:
whatever is below - set to zero.

Liping, Ilya, Ashot,

Currently, in the MC simulation, the energy threshold for a detector to be included in a cluster is calculated from the data gains ie it is varying from detector to detector and is run-dependent. To minimize the systematics should we leave the situation as it is or think of a different approach. I am thinking (naively) that it might be better to set this threshold to value at least 20 to 30% to what it is actually and possibly to set the threshold in a way that is the same for most detectors, and all runs both in data and simulation. What are your inputs in this or what did you do in previous PRIMEX measurements?

tks ig.
