easiest is to create a new plot, that shows what you want to know.
The launcher file also produces a result object, if you need help with this class type:
doc simulation.results.ResultsPartial in the command prompt (assuming you are in the main folder of the simulator, otherwise you need to change the path).
In the networkElements property of this class you can find all information about the base stations and users and their types (i.e. macro, femto, clustered, ppp) and positions. In this simulation all users and base staions are static, so it is sufficient to plot the first position in the positionList. Make sure you get the position of the base stations from their associated antennas.
If you have trouble with the userList or the baseStationList try:
doc networkElements.bs.BaseStation and
To know which users are associated to which base station, you can look at result.assignedBS, if you need help with this class type:
doc simulation.results.ResultsPartial.assignedBS in the command prompt.
There you find which user is associated with which base station. Again, since all users are static, it is sufficient to look at the assignedBS in the first slot.
