4.4.50 SUBROUTINE ZTDTPM(NAME,ILAY,MESPAR,IDET) : DeTector Position Measurement parameters

Routine to return the track or shower position measurement parameters 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 :

    MESPAR(1:5) : Shower energy measurement parameters:
                1 : position error in Rphi (barrel) or x (forward)
                2 : position error in z (barrel) or y (forward)
              for calorimeters also:
                3 : error on theta of shower axis
                4 : error on phi of shower axis
                5 : type of position measurement of the calorimeter:
                     0 : Realy measures
                   <>0 : Only module hit known and error are the
                         module size in the direction divided by
                         sqrt(12). No shower axis direction
                         determination done, hence mespar(2:3) are nil.
                         Specifically:
                            mespar(5) =
                               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)
    IDET : detector type:
            1 : barrel tracking
            2 : forward tracking
            3 : barrel calorimeter
            4 : forward calorimeter
