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 .

The current public version of cWB (cWB-6.4.3.4) is fully compatible with the one used for the LVK O3 analysis. The previous version, cWB-6.4.1 can also be found on:

Important
Somewhat outdated materials have also been reported mainly for reference and are marked as

Nethertheless, since documentation update is not complete yet, it is not guaranteed that all outdated pages are marked so.
Attention
The cWB has been developed for Linux operating systems. It is configured to work on Linux distributions such as:
- Scientific Linux 7.x
- Rocky Linux 8
- Debian GNU/Linux buster, bullseye, bookworm
cWB can also be used with other Linux distributions or with OSX (with some minor modifications) but it is not officially supported.
