HMmmm, I don't know what's going on there. Basically your output, as far as Vector is concerned, is PAW only. You don't have ADSB or Flarm, so the Vector system should only be seeing PAW. Strange that in the first diagram (where ALL was selected) is showed a much greater coverage and a significant increase in the number of 'hits' compared to the second. I would have expected them to be the same.
Mode S/MLAT is not included in the polar diagram, so I wonder why there is such a big difference between selecting PAW only and ALL, when the aircraft has PAW alone (as far as Vector is concerned)?
