Detailed Description

CbmStsMapsHit Class for MAPS detector hit

Author

Michael Deveaux m.dev.nosp@m.eaux.nosp@m.@gsi..nosp@m.de Acknowledgements to M. Al-Turany, D. Bertini, G. Gaycken Version beta 0.1 (02.02.2005) Slight modifications by V. Friese to match coding conventions

Meaning of RefIndex: Index of corresponding MCPoint -1 if fake or background hit

Meaning of Flag: 0 = Hit ok -1 : Hit lost due to detection inefficiency
