[Gate-users] adder for exact Compton kinetics analysis

Currently the adder (part of digitizer) module of GATE behaves like this:
For the level defined,
timestamp: keep the timestamp of the 1st hit
energy: sum all hits
localization: energy-weighted centroid of all hits
However, this poses problems when one wants to analyze inter-crystal
behavior using the exact Compton kinematics law, since the hits include a
lot of photoelectron/recoil electron hits as well. One would require an
adder that has a different localization behavior:
Modified Localization: energy-weighted centroid of all *photon*
hits, where the energy of a single photon hit is its own plus all the e-
interaction from its displaced electron.
Has anyone used/built such an adder? If so, I'm interested in discussing my
eventual "sharing" of it.
Would it be of general interest to include it in the public release if I
build one? Right now, such a custom adder requires processing of the ascii
hit file, which because of sheer size is impractical on a regular basis.
