- The observation lines and areas take note of the direction of the power and therefore the sign indicates this direction. In the case of your observers positive power corresponds to power moving in the +ve Z direction and similarly negative power corresponds to power moving in the -ve Z direction.
- Your procedure is effectively correct.
- This will depend on what you mean by “raw data” are you looking for the fields? Within the detector analysis there is an export data button which will allow you to export the spectrum. Similarly if you are viewing field data you can export that.
