4.4.49 SUBROUTINE ZTDTGE(NAME,ILAY,GEOPAR,IDET,CALTYP) : DeTector GEometry

Routine to return the geometry of a given sub-detector

ARGUMENTS:

INPUT :

    NAME : Name of the sub-detector
    ILAY : The layer number. If =0, then the fiirst layer is used.

OUTPUT :

    GEOPAR(1:7) : Detector Geometry parameters:
                1 : R (barrel) or z (forward)
                2 : minimal z (barrel) or R (forward)
                3 : maximal z (barrel) or R (forward)
            For calorimeters also:
                4 : type of position measurement of the calorimeter:
                     0 : Realy measures
                   <>0 : Only module hit known, no shower axis direction
                         Specifically:
                            geopar(4) =
                               1 : modularity is in phi and z (barrel) or
                                   $\phi$ and R (forward)
                               2 : modularity is in phi and theta
                                   (barrel) or x and y (forward)
                5 : minimal phi of the first module, if modules
                    are modular in phi. The "first" module is the
                    module that is closest to the x axis (counter-
                    clockwise), but doesn't cross the x-axis.
                6 : Number of modules in the first direction
                7 : Number of modules in the second direction

    IDET : detector type:
            1 : barrel tracking
            2 : forward tracking
            3 : barrel calorimeter
            4 : forward calorimeter
     CALTYP : calorimeter type
            0 : not a calorimeter
            1 : Em calorimeter
            2 : hadronic calorimeter
            3 : dual-purpose calorimeter

IMPLICIT INPUTS:

    From /ZTXRD/ : LAYNAM, list of layer-names; LAYSET, set of
           layers with a given name; DETTYP, detector-type for
           a given name.

IMPLICIT OUTPUTS:

    none.
