Route resolved from the callsign: Chicago O'Hare International Airport (KORD) to Rome–Fiumicino Leonardo da Vinci International Airport (LIRF), confidence 60/100. A deduction from the reference data, never a measured path.
First and last received points. Two measurements, nothing in between.
'Entry' and 'exit' mark where the station began and stopped receiving the aircraft, at the edges of the antenna's range: not where the aircraft appeared or vanished.
