GW150914: First results from the search for binary black hole coalescence with Advanced LIGO, The LIGO Scientific Collaboration, the Virgo Collaboration
“In addition to possible gravitational-wave signals, the detector strain contains a stationary noise background that primarily arises from photon shot noise at high frequencies and seismic noise at low frequencies.”

    “its false alarm probability is not sufficiently low to confidently claim this candidate event as a signal. Detailed waveform analysis of this candidate event indicates that it is also a binary black hole merger with source frame masses 23+18 M⊙ and 13+4 M⊙, if it is of astrophysical origin.”
