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