Element# : 1 Contents : Word count of each cluster. Format : I*2
HBUF(í)=Number of words of i-th cluster.
Element# : 2
Contents : Compressed cluster information.
Format : I*2, R*4 mixed.
Each cluster informations are stored in a single element after data compressions
2cm HBUF(1)(1:NW1), HBUF(2)(1:NW2), ... HBUF(n)(1:NWn)
where index of HBUF corresponds to the cluster number, n is a total number of cluster which is equal to the number of element of the bank "Production:EMC;Cluster", and NWi is the number of words for i-th cluster. NWi may be different cluster by cluster and it is stored in the element # 1 of this bank. HBUF(i) contains the cell number, namely the element number of "Production:EMC;Hit_Cell" contributing to the i-th cluster.
