The DELPHI Silicon Tracker in the global pattern recognition

ALEPH and DELPHI were the first experiments operating a silicon vertex dete ctor at LEP. During the past 10 years of data taking the DELPHI Silicon Tra cker was upgraded three times to follow the different tracking requirements for LEP 1 and LEP 3 as well as to improve the tracking performance. Severa l steps in the development of the pattern recognition software were done in order to understand and fully exploit the silicon tracker information, Thi s article gives an overview of the final algorithms and concepts of the tra ck reconstruction using the Silicon Tracker in DEL-PHI.
