Detailed Description

Standard filter for gamma-rays (EUROBALL-like appproach)

Gamma-ray simulated with BaseGEM or GEM could be used as inputs for detector simulations. The GEANT simulations give then the expected events coming from a 'real' experiment.

In order to produce events faster (probably needed to produce large amount of DATA), one can define some global characteristics of the AGATA array and use this experimental filter to get as much as possible realistic events. This approach is standard because the detector is supposed to be characterised only by its efficiency, its peak to total, its resolution and a compton profile. It allows then some comparisons with, for instance, EUROBALL. A more complex approach (TrackFilter) should be available soon ..
The list of gamma-rays is modified by taking into account:

An efficiency curve.
For a given gamma-ray energy, it says if the gamma-ray is detected or not.
A peak to total ratio
For a given gamma-ray energy, it says if the gamma-ray is fully detected (photopeak event). If not the g-ray energy is changed
A doppler broadring
For a given gamma-ray energy, it gives a Gaussian distribution.
