crude clustering
Super clusters are constructed by using crclust function and complete algorithm for clustering has been adopted
constants used for calculating coordinate of neighbouring cells
initialize infocl[2][96][72]
crude clustering begins. Start with cell having largest adc count and loop over the cells in descending order of adc count
icl –cluster #, numcell – # of cells in a cluster, clust – stores coordinates of the cells in a cluster, infocl[0][i1][i2] is 1 for primary and 2 for secondary cells, infocl[1][i1][i2] stores cluster #
check for adc count in neighbouring cells. If ne 0 include them in this clust

refined clustering
Breaking of super clusters into smaller clusters, Cluster positions,strengths,and widths has has been calculated by adopting minimization process.
clno counts the final clusters nsupcl = # of superclusters; ncl[i]= # of cells in supercluster i
