Member Function Documentation

◆ EffectiveRadius()

double ClusterTools::EffectiveRadius ( const ant::TCluster &  cluster) const

Calculate the Effective Radius of a cluster.

Parameters
cluster
Returns

\[ eff = \sqrt{\frac{\sum_{i=0}^{n} E_i (\Delta r_i)^2 }{ (\sum_{i=0}^{n} E_i) }} \]

where $ \Delta r_i $ is the opening angle (in degrees) between the cluster direction and the crystal axis.

In contrast to the lateral moment, the two highest energetic crystals are weighted the same as every other crystal.

◆ LateralMoment()

double ClusterTools::LateralMoment ( const ant::TCluster &  cluster) const

Calculate the Lateral Moment of a cluster.

Parameters
cluster
Returns

\[ lat = \frac{\sum_{i=2}^{n} E_i r_i^2 }{ (\sum_{i=2}^{n} E_i r_i^2 + r_0^0 E_0 + r_0^2 E_1) } \]

where $ E_{0} $ and $ E_{1} $ are the two hits highest energies.

Reimplemented after BaBar
