-/* --------------------------------------------------------------------
- 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

- Proposed changes inNMX, kNDIMX and kNDIMY by S. C. Phatak to account
- for rectangular ( vs rhomboid ) geometry.
- To keep the clustering functional, we define a rhomboid which
- superscribes the rectangle. So we need to pad up dummy cells in x
- direction. The number of these cells is 96/2-1=47 in each row ( value
- of x ). For first two rows, all dummy cells are to the left. For
- every two rows add one cell to right and subtract one from left.
- So previous (i,j) values go over to ( i',j) i'=i+(96-j)/2-1
- Note we use C++ convention so i and j run from 0 to 47 or 95.
