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.

You can find the special meanings of values { 0, 254, 255} in section 3.4.1 of https://www.te.rl.ac.uk/esdg/cms-fed/firmware/Documents/FE_FPGA_Technical_Description.pdf
