/**
  * @brief Creates the Effect Show data from the Area Effect Simulation data for Explosion Clusters.
  *
  * For the Effect Show data to be created see ICD GUEZSB60_ICD-0046C.
  * For calculations the mathematical x-axis is mapped to east; the y-axis is mapped to north.\n
  *
  * List of features:\n
  * (1)The area effect is limited to one effect show located at the center of the cluster.\n
  * (2) Only specific charge types create more than one effect show as configured in the charge type
  * (3)The number of volleys depends on the number of shots by the explosion cluster as follows:\n
  *    Number of shot <= 25  : 3 volleys\n
  *    Number of shot <= 50  : 6 volleys\n
  *    Number of shot <= 100 : 9 volleys\n
  *    Number of shot <= 150 : 12 volleys\n
  *    Number of shot <= 200 : 15 volleys\n
  *    else                  : 18 volleys\n
  * (4)The start time for the effect show is overtaken from the start time of the explosion cluster.\n
  * (5)The duration for the effect show is overtaken from the duration of the explosion cluster.\n
  * (6)The type of ammunition is determined by the chargeType of the explosion cluster and the
  *    "tas code indirect" of the Project Data Management.\n
