Detailed Description

Algorithm which makes a egammaObjectCollection for forward electrons. egammaForwardBuilder, is dedicated to the reconstruction and identification of electrons in the forward region of ATLAS (2.5<|eta|<4.9). In contrast to the softe and egamma builders the algorithm can use only the information from the calorimeters, as the tracking system is limited to |eta|<2.5, and the topological clusters (instead of SW clusters). The pre-selection and ID are done in the same algorithm. The variables used to discriminant between electron and hadrons are defined as the topo cluster moments or combination of them. This is done separately in two eta bins: the EMEC IW and the FCal using a cut based technic. The forward electron AUTHOR is 8.

Declare a new Gaudi property.

Parameters

name	Name of the property.

Parameters
