GWTC-3: Compact Binary Coalescences Observed by LIGO and Virgo During the Second Part of the Third Observing Run — Glitch modelling for events
Description
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/).
Glitch model for GWTC-3 events
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. The names and sample rates (in Hz) of the channels in these files are
