 OUT        1    CHAR       Dataset into which simulated
                            events will be put
            -> GLOBAL.EVDS (Default event dataset)
 MODEL      -    UNIV       A background model
      Default !
 FIELDSIZE  -    REAL       The full width of the field in arcmin
          Default 60.0

          Default 1.0
 SEED       -    CHAR       The seed for the random number generator.
                            If specified, EVSIM will not poisson
                            deviate the source and background counts.
                            This provides a method of re-creating a
                            previously constructed dataset.
