Here we describe how to perform the analysis of GWTC-1 Catalog events with the coherent WaveBurst pipeline.

What you need is cWB on your computer and the event data released in the Gravitational Wave Open Science Center ( GWOSC ).

The easiest way to start using cWB on your computer is to install an “image” of cWB within a “virtualized” environment: you can freely choose between the cWB VirtualBox image and the cWB Docker container.

Instructions on how to run cWB on VirtualBox and Docker are reported in the cWB User Manual, here and here, repectively.

Once you have a working cWB installation (VitualBox, Docker, or directly installed on your system) you will be able to do some basic testing on the list of public confident detections from GWTC-1 (the Gravitational-Wave Transient Catalog of Compact Binary Mergers Observed by LIGO and Virgo during the First and Second Observing Runs) as reported in the GWOSC.

The analysis of GWTC-1 Catalog events can be easily performed with a dedicated cWB command: cwb_gwosc.

The command line to execute the full analysis of GW150914 event is:

    cwb_gwosc GW=GW150914 all

The output of the previous command is the Coherent Event Display ( CED ) of the GW150914 event. See the CEDs of the GWTC-1 Catalog
