Analysis of information sources in references of the Wikipedia article "LIGO" in English language version.
This is equivalent to measuring the distance from Earth to the nearest star to an accuracy smaller than the width of a human hair!(that is, to Proxima Centauri at 4.0208×1013 km).
LIGO's advanced detectors are already three times more sensitive than Initial LIGO was by the end of its observational lifetime
The bottom line is that [the sensitivity] is better than it was at the beginning of O1; we expect to get more detections.
the start of O3 is currently projected to begin in early 2019. Updates will be provided once the installation phase is complete and the commissioning phase has begun. An update on the engineering run prior to O3 will be provided by late summer 2018.
