Detailed Description

EMConversion data object builder. This is an Algorithm class. Selects conversion vertices reconstructed by the ID software after matching them to an EM calorimeter cluster. For normal two-track conversions the original photon track parameters at the conversion vertex are reconstructed. It is then extrapolated to the calorimeter and checked whether it matches the cluster. For single-track conversions, the reconstructed electron track is extrapolated to the calorimeter. A TrackToCalo extrapolation tool that can handle both neutral and charged track parameters (using a Trk::ParametersBase interface) is used throughout. The extrapolation starts at the last track measurement. Matching is done in both eta and phi. The eta matching WAS disabled for TRT-only tracks due to lack of accurate eta prediction BEFORE 12/2011.
