coherent WaveBurst

coherent WaveBurst (cWB) is a data-analysis tool to search for a broad range of gravitational-wave (GW) transients. The pipeline identifies coincident events in the GW data from earth-based interferometric detectors and reconstructs the gravitational wave signal by using a constrained maximum likelihood approach. coherent WaveBurst was the first algorithm to identify the gravitational wave signal GW150914 detected by LIGO .

Note

The cWB library is being made available under the:

Note

The current public version of cWB (cWB-6.3.0) is compatible with the version used for the analysis of O2-RUN data (wat-6.2.6).

Important

Some instructions and documents reported in this manual are addressed only to LIGO-Virgo Collaboration (LVC) / cWB developers or for Public Version users.

Important

Not updated material is marked as TBU. Nethertheless it is not guarantee that all instructions not marked as TBU are updated. The update of the manual is in progress.

Attention

The cWB has been developed for linux operating system. The Linux distributions used sofar are;

  • Scientific Linux 7.6
  • Debian GNU/Linux jessie, stretch, buster

cWB can be used also with OSX (with some minor modifications) but is not officially supported.
