Our data files of cleaned 4096 seconds strain data around GW150914 (uploaded August 21, 2017)
The data is presented in two columns: The first shows the time-ordered, cleaned data for Hanford, the second shows that for Livingston. The sampling rate chosen is 16384 Hz. The GPS time marking the start of both files is 1126257414.
Alternatively, the Hanford and Livingston cleaned data can be downloaded in separate files:
Cleaned Hanford data, 4096 seconds, sampling rate 16384 Hz (uploaded August 22, 2017)
Cleaned Livingston data, 4096 seconds, sampling rate 16384 Hz (uploaded August 22, 2017)
