4.3.20 SUBROUTINE ZDCCCC(ICAL,CTYP,CELLCENT,SHOAX) : Calorimeter Cell Centre Coordinates

This routine returns the correct two coordinate of the centre of a calorimeter module.

ARGUMENTS:

INPUT :

    ICAL : number of the calorimeter.
    CTYP  : +ve : Cylindrical detector.
            -ve : Plane detector.
    CELLCENT : coordinates of the cell centre in the system
               in which the calormiter is modular
               described by, ie :
      Barrel :
         (phi,z)  (type=1) or (phi,theta) (type=2)
      Forward :
         (phi,R)  (type=1) or (x,y) (type=2)

OUTPUT :

    SHOAX  : Shower axis and direction :
                (1) First module centre    (barrel : Rphi, forward : x)
                (2) Second  "       "      (barrel : z, forward : y)
                (3) Seen shower theta angle
                (4) Seen shower phi angle
              (The shower-axis direction is just the direction of the
              line from the origin to the shower start-point)
