Update on #S190426c
https://gcn.gsfc.nasa.gov/gcn3/25549.gcn3
Probabilities of astrophysical/noise origin have been revised. It now looks to probably be noise (68%)
If you assuming that it's real, based upon inferred masses it still looks to most probably be in the NSBH...

Update on analysis of #S190426c. If you're happy to assume it's real, based upon preliminary parameter estimation, we see that estimates for the mass give relative probabilities of being classed as a NSBH:MassGap:BNS:BBH are approximately 12:5:3:0...

Thanks to those who worked late into the night, here's an updated estimate of the source location for #S190426c Northern hemisphere now looking more probable. LALINference1.fits.gz available from https://gracedb.ligo.org/superevents/S190426c/view/

@ego_virgo @LIGOWA @LIGOLA Here's is the Circular about #S190426c https://gcn.gsfc.nasa.gov/gcn3/24237.gcn3 We've now done the first checks that the instruments are OK. We'll continue performing data quality checks

@ego_virgo @LIGOWA @LIGOLA This is the initial three dimensional localization for #S190426c. The panels are three views, with the 🜨 representing the Earth. The distance is around 400 Mpc, about 10 times bigger than for GW170817, which could mean any counterpart would be faint

@ego_virgo @LIGOWA @LIGOLA Here is the initial sky map for candidate #S190426c. THe red areas are more probable. We have data from all three detectors, so this is much better than for #S190425z. If real, this could be a binary neutron star or a neutron star–black hole, either could...

@ego_virgo @LIGOWA @LIGOLA Currently on the parameter estimation rota is Aaron Zimmerman, who was also on rota for GW170104 and much of August 2017, so we were expecting something interesting to happen #S190426c

be sure #S190426c

A new #GravitationalWave candidate #S190426c https://gracedb.ligo.org/superevents/S190426c/view/
This is low significance, but covers the neutron star–black hole mass range
