- Code developed by S. C. Phatak, Institute of Physics,
- Bhubaneswar 751 005 ( phatak@iopb.res.in ) Given the energy deposited
- ( or ADC value ) in each cell of supermodule ( pmd or cpv ), the code
- builds up superclusters and breaks them into clusters. The input is
- in array d[ndimx][ndimy] and cluster information is in array
- clusters[5][5000]. integer clno gives total number of clusters in the
- supermodule.
-
- d, clno and clusters are the only global ( public ) variables. Others
- are local ( private ) to the code.
-
- At the moment, the data is read for whole detector ( all supermodules
- and pmd as well as cpv. This will have to be modify later )
-
- LAST UPDATE : October 23, 2002
