CED

The first screenshot of GW150914 event

This is a copy of the original CED which triggered the attention of all the LIGO/Virgo Collaboration due to its strength and chirping morphology.

#GWTC-1 #O1 #CED #HL

This GW event was reconstructed by lowering the subnet threshold (from 0.5 to 0.0, i.e. allowing the reconstruction of GW events for which the Signal-to-Noise Ratio on one detector is much higher than on the others).

Note: In order to generate a skymap over the full sky area, this CED has been produced by setting the netCC=0.

This GW event was reconstructed by lowering both the subnet threshold (from 0.5 to 0.0, i.e. allowing the reconstruction of GW events for which the Signal-to-Noise Ratio on one detector is much higher than on the others) and the netRHO (from 5.5 to 4.5, i.e. allowing the reconstruction of weaker GW events).

Note: In order to generate a skymap over the full sky area, this CED has been produced by setting the netCC=0.

Due to a large noise glitch in Livingston data which overlaps with GW170817, this GW event can only be reconstructed using special frames with the glitch removed. See [DCC document T1700406](https://dcc.ligo.org/LIGO-T1700406/public). [GW170817 Press Release](https://www.ligo.caltech.edu/page/press-release-gw170817)

Posted on Saturday, Jan 5, 2019

This was the first direct observation of a gravitational-wave signal. Its detection by the LIGO and Virgo Collaboration was triggered by cWB, which was the first algorithm that identifed GW150914. GW150914 Press Release
