GWTC-3: Compact Binary Coalescences Observed by LIGO and Virgo During the Second Part of the Third Observing Run — Glitch modelling for events

This material is part of several data products associated with GWTC-3, the third Gravitational-Wave Transient Catalog from the LIGO Scientific Collaboration, the Virgo Collaboration, and the KAGRA Collaboration. For more information, see the paper (dcc.ligo.org/LIGO-P2000318/public), the related material linked from this page, and the GWTC-3 data release documentation (www.gw-openscience.org/GWTC-3/). <strong>Glitch model for GWTC-3 events</strong> Glitch model for events in the GWTC-3 catalog that used either BayesWave glitch subtraction or linear noise subtraction. Each data file for events processed with BayesWave contain three channels: The calibrated strain data, including any glitches that are present, A model of the glitches, produced using the BayesWave algorithm, The calibrated data with the glitch model subtracted, used for parameter estimation. Each data file for events processed with linear noise subtraction contain one channel: The calibrated data with the glitch linearly subtracted, used for parameter estimation. LIGO Hanford data for events GW191109_010717, GW191113_071753, GW191127_050227, and GW191219_163120 was generated with BayesWave.
