This system is the lightest black hole binary so far observed, with componentmasses of 12⁺⁷ <inf>-2</inf>M<inf>⊙</inf>7⁺² <inf>-2</inf> (90% credible intervals). These lie in the range of measured black hole masses inlow-mass X-ray binaries, thus allowing us to compare black holes detected through GWs with electromagneticobservations. The source's luminosity distance is 340⁺¹⁴⁰ <inf>-140</inf>corresponding to redshift -0.07^+0.030 <inf>03.</inf> We verify thatthe signal waveform is consistent with the predictions of general relativity.truebinaries: general | gravitational waves | stars: black holesArticlehttps://kclpure.kcl.ac.uk/ws/files/83571730/GW170608_Observation_of_a_19_LIGO_Published18December2017_GREEN_VoR.pdf2041821320 December 20171013L35arJournal974
