Data release for event GW150914
Online — A web page has been prepared on the Ligo Open Source website by the LIGO Scientific Collaboration (LSC) and the Virgo Collaboration to inform the broader community about a confirmed astrophysical event observed by the gravitational-wave detectors, and to make the data around that time available for others to analyze.
This dataset has the Digital Object Identifier (doi) http://dx.doi.org/10.7935/K5MW2F23.
Summary of Observation
The event occurred at GPS time 1126259462.39 == September 14 2015, 09:50:45.39 UTC.
The false alarm rate is estimated to be less than 1 event per 203,000 years, equivalent to a significance of 5.1 sigma.

LIGO: The Laser Interferometer Gravitational-Wave Observatory
LIGO is a large-scale physics experiment designed to directly detect gravitational waves. The LIGO detectors, at the LIGO Hanford Observatory (LHO) in Washington State and the LIGO Livingston Observatory (LLO) in Louisiana, are built and operated by Caltech and MIT with funding from the U.S. National Science Foundation (NSF). The LIGO Scientific Collaboration (LSC) pursues gravitational wave science with these detectors. The initial and enhanced LIGO detectors operated from 2000 to 2010, with no confirmed detections. The Advanced LIGO detectors are coming online in 2015, along with sister projects around the world. They are expected to detect gravitational waves, and measure the properties of the waves and their astrophysical sources, in the coming years.
Laser Open Sciece Center (LOSC) Development: The LOSC Team and The LIGO Scientific Collaboration
The data products made available through the LOSC web service are created and maintained by LIGO Lab and the LIGO Scientific Collaboration. The development of the web page was a team effort, with all members of the LOSC team making contributions in most areas.
In addition to the team members listed below, a large number of individuals in the LIGO Scientific Collaboration have contributed content and advice. The LOSC team includes:
- Alan Weinstein: LOSC Director
- Roy Williams: LOSC Developer, web services and data base architecture
- Jonah Kanner: LOSC Developer, tutorials, documentation, data set curation
- Michele Vallisneri: LOSC Developer, data quality curation
- Branson Stephens: LOSC Developer, event database and web site architecture
