C                   SAME LAYER)

C                       TRACK ; DOES NOT EXIST FOR THE 1ST AND 2ND WIRE
C                       OF EACH TRACK)

C     MB(1,M+1) : POINTER (LEVEL 2) TO THE PREVIOUS COMB. BANK
C                 LEVEL 1 AND 2 MEANS :
C                 LEVEL 1 POINTS TO ANOTHER TRACK WHICH FITS TO WIRES
C                         OF THIS CLUSTER. ALL WIRES WHICH CAN BE
C                         REACHED VIA THIS KIND OF POINTERS ARE
C                         THE INNERMOST WIRES OF A TRACK.
C                 LEVEL 2 POINTS TO THE PREVIOUS WIRE OF THE SAME TRACK
C                         OR TO TO THE SAME TRACK / WIRE COMBINATION

C                            THE POINTERS ARE ORDERED ACCORDING
C                            TO THE QUALITY (SEE BELOW).
C                 IT IS PROVIDED THAT EACH ASS. BANK CAN BE REACHED
C                 IN ONLY ONE WAY USING THESE CHAINS OF POINTERS.
C     BM(2,M+1) : DELTA PHI = AZIMUTHAL DIFFERENCE BETWEEN THE CURRENTLY
C                 DESCRIBED WIRE AND THE PREVIOUS ONE.

C     BM(2,M+2) : D PHI / D R OF THE TRACK IN THIS LAYER (APROXIM : ONLY
C                 THE SIGN IS CORRECT)

C     BM(2,M+5) : DELTA PHI BETWEEN THIS WIRE AND THE LAST BUT ONE WIRE

C                     BUT IN DIFFERENT LAYERS)

C     MB(1,M  ) : NEXT NEIGHBOUR BANK
C     BM(2,M  ) : ZERO OR +- 2*PI TO BE ADDED TO THE AZIMUTHAL DIFF.
C     MB(1,M+1) : 1ST WIRE IN THE NEIGHBOURING CLUSTER
C     MB(2,M+1) : LAST WIRE IN THE NEIGHBOURING CLUSTER
