Data release associated with publication 'GW190425: Observation of a compact binary coalescence with total mass ∼ 3.4 M⊙': https://dcc.ligo.org/LIGO-P190425/public Parameter estimation samples are available: https://dcc.ligo.org/LIGO-P2000026/public Data sourced from: FrameChannels: [ L1:DCS-CALIB_STRAIN_CLEAN_C01, V1:Hrec_hoft_16384Hz ] FrameTypes: [ L1_HOFT_C01, V1Online ] To open GWF files, use channel names as shown for GWTC-1: https://doi.org/10.7935/82H3-HH23 Parameter estimation for the associated discovery paper subtracted a glitch model from these data as a pre-processing step. The glitch model used is available at: https://dcc.ligo.org/T1900685/public In the 4096 second time window surrounding GW190425, there were multiple instances where a CBC and BURST CAT2 veto was active. These times are related to excess noise due to vibrations from an automated camera shutter that was operating in the End Y station. This periodic noise source is well localized in both time and frequency, and did not impact analyses of GW190425. Parameter estimation information was updated August 21, 2020 to reflect published values.
