Extended Examples9.2.1. Extended Example SummaryGeant4 extended examples serve three purposes:• testing and validation of processes and tracking,• demonstration of Geant4 tools, and• extending the functionality of Geant4.The code for these examples is maintained as part of the categories to which they belong. Links to descriptionsof the examples are listed below.9.2.1.1. Analysis• A01 - hit-scoring and histogramming using the AIDA interface• AnaEx01 - histogram and tuple manipulations using an AIDA compliant system281
