Member Function Documentation

const std::vector<uint8_t>& SiStripCluster::amplitudes ( ) const

inline

The amplitudes of the strips forming the cluster. The amplitudes are on consecutive strips; if a strip is missing the amplitude is set to zero. A strip may be missing in the middle of a cluster because of a clusterizer that accepts holes. A strip may also be missing anywhere in the cluster, including the edge, to record a dead/noisy channel.
