168:. The Livingston detector was the first to receive the signal, followed by the Hanford detector 8 milliseconds later and Virgo received the signal 14 milliseconds after Livingston. The detection in all three detectors lead to a very accurate estimate of the position of the source, with a 90% credible region of just 60
