GWTC-2.1: Deep Extended Catalog of Compact Binary Coalescences Observed by LIGO and Virgo During the First Half of the Third Observing Run - Glitch modelling for events

This material is part of several data products associated with GWTC-2.1, the deep extended catalog of compact binary coalescences observed by the LIGO Scientific Collaboration and the Virgo Collaboration during the first half of the third observing run. For further information, see the paper (dcc.ligo.org/LIGO-P2100063/public), the related material linked from this page, and the GWTC-2.1 data release documentation (www.gw-openscience.org/GWTC-2.1/).

Glitch model for GWTC-2.1 events

Glitch model for events in the GWTC_2.1 catalog that used BayesWave glitch subtraction. This includes LIGO Livingston Observatory (L1) data for the following events:

• GW190413_134308
• GW190425_081805
• GW190503_185404
• GW190513_205428
• GW190514_065416
• GW190701_203306
• GW190924_021846

Each data file contains three channels:

1. the calibrated strain data, including any glitches that are present,
2. a model of the glitches, produced using the BayesWave algorithm,
3. the calibrated data with the glitch model subtracted, used for parameter estimation

For the L1 data for all events, these channels have the following names and sample rates (in Hz):

1. L1:DCS-CALIB_STRAIN_CLEAN_SUB60HZ_C01 16384
2. L1:DCS-CALIB_STRAIN_CLEAN_SUB60HZ_C01_glitch 16384
3. L1:DCS-CALIB_STRAIN_CLEAN_SUB60HZ_C01_T1700406_v4 16384
