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