C
C  DTXPN0 : CUT DEFINING A CLUSTER OF WIRES (WIRES IN THE SAME LAYER;
C           MEASURED IN NUMBER OF WIRES). IF THE LARGEST GAP
C           BETWEEN ANY (< 32) NUMBER OF SUBSEQUENT WIRES IS
C           SMALLER THAN DTCPN0, THESE WIRES ARE HANDLED AS ONE
C           CLUSTER.
C
C  DTXPN1 : CUT DEFINING THE WIDTH (AZIMUTHAL DIRECTION) OF THE
C           WINDOW (MEASURED IN NUMBER OF WIRES). A TRACK IS
C           EXTENDED, I.E. A NEW WIRE IS ASSIGNED TO A GIVEN
C           TRACK, IF THE PREVIOUS (= UP TO NOW LAST) WIRE OF THIS
C           TRACK IS WITHIN THIS WINDOW. N.B.: THIS CUT IS APPLIED
C           ONLY IF THE PREVIOUS WIRE IS IN A DIFFERENT LAYER THAN
C           THE NEW ONE; OTHERWISE SEE : DTCPN0.
C
C  DTXPN2 : SAME AS DTCPN1 BUT USED FOR THE TRACK INITIALIZATION
C           IF THE 1ST,2ND, AND 3RD WIRE ARE IN DIFFERENT LAYERS.
C           THE CUT IS APPLIED ON THE AZIMUTHAL DIFFERENCE
C           (MEASURED IN NUMBER OF WIRES) BETWEEN THE 1ST AND 3RD WIRE.
C
C  DTXPN3 : SAME AS DTCPN2 BUT USED IF THE 1ST, 2ND, AND 3RD WIRE
C           ARE NOT IN DIFFERENT LAYERS.
C
C  LDTXTR : CUT DEFINING THE LENGTH (RADIAL DIRECTION) OF THE WINDOW
C           (SEE : DTCPN1 ; MEASURED IN NUMBER OF LAYERS).
C
C  LDTXT3 : SAME AS LDTCTR BUT USED FOR THE 2ND AND 3RD WIRE OF A TRACK.
C
C  LDTXT2 : SAME AS LDTCTR BUT USED FOR THE 1ST AND 2ND WIRE OF A TRACK.
C
C  DTXUR1 : MAXIMUM CURVATURE = 1 / (2 * RADIUS / CM)
C
C  DTXUR2 : SAME AS DTCUR1 BUT USED FOR THE TRACK INITIALIZATION
C           IF THE 1ST,2ND, AND 3RD WIRE ARE IN DIFFERENT LAYERS.
C
C ATTENTION! THE ABOVE CUTS CAN BE FREELY CHANGED WITH "TALK_TO ATFMOD",
C            AS WELL AS RELOADED WITH INITIAL DEFAULTS.
C 
C THE ORIGINAL DEFAULTS, FILLED IN A BLOCK-DATA AND INACCESSIBLE,
C ARE KEPT IN VARIABLES WITH SIMILAR NAMES, SUBSTITUTING 'DTX-->DFC'
