Changelog

cWB has been in active development since 2003 and it has been used to analyze all scientific data collected by the LIGO-Virgo detectors ever since. In 2009 the project migrated a first time to SVN. In 2018, it migrated a second time on git. Since 2019, cWB sources are released publicly on gitlab.com.

cWB public releases

cWB-6.4.1 - 2021-12-23

  • Highlights

    This new release ( cWB-6.4.1 ) is a major upgrade of cWB: it fixes minor problems with the previous version and it introduces some new functionalities in the cwb_gwosc command. It is fully compatible (i.e. in terms of results) with the version used for the latest analyses/results on the LIGO-Virgo data collected during the Third Observing run O3.

  • Release Notes

    • Added functionality: GWTC 3 events summary
    • cwb_gwosc command extended to include the latest released events from O3b
    • Minor improvements and fixes
    • Besides the old installation system, based on ad-hoc tailored Makefiles, we are currently testing a cmake installation, which will hopefully make it easier to install cWB. Though, this new feature is already functional,

    we are still not recommending it as the default installation method.
