nice page tyr but I actually read it before I asked. It has only 4 sentence within, that has "ECM" in it.
1) Note that overlapping scanning zones improve the scanner efficiency and reduce the chance of ECMs to protect any target.
2) All entities that are in range (i.e. on a square of your scanner grid where power > 0) and with stealth (for char) or ECM (for others) is strictly lower than the total sensor power on their square.
3) You can initiate a focus scan on any entity (except characters) in range of your sensors. This scan will provide you more detailed information about that entity like weaponry, sensors, ECM and so on.
4) If your sensors are higher that the target's ECM, then you will also know the number of passengers, ships and vehicles onboard the target.
the only one which has something to do with my question is 2) but it doesn't say enough. what is [strictly lower]?
after all I asked, if space stations with ECMs are displayed on the map without having them in sensor range. if you are on system grid 1,1 have 1 sensor and there is a shipyard at 7,7 you still see it on your map. If that's the same with ECM SS it would be somewhat contraproductive, wouldnt it?
