Which can be used, for example, as follows:

channel = bb18order( channel )
       ch = channel + ( module - 1 ) * 64 + ( range * 2048 )

where channel (ASIC channels # 0-63), module (FEE #) and range (0=LEC/MEC, 1=HEC)
are supplied by the GREAT format data item.

Attachments 1-7 - 2D hit pattern showing which (if any) other channels j are active
( hit(j) = .true. ) in an event (< 410 clock cycles) in addition to channel i

       IF ( hit( i ) ) THEN
        DO j = i, 767
         IF ( hit( j ) ) THEN
