Abstract:
GPS start and stop times of segments used for creation of standard set of Short Fourier Transforms from O2 data. For broadband searches or others that are prone to narrow spectral detector artifacts, it is recommended to avoid periods of severe spectral contamination by using the "minusContaminatedPeriod" files. [1] These segments use analysis ready cleaned C02 data minus CAT1 vetoes. Note that 300s of additional data is present for the H1 data compared with the GWOSC data set because one final DQ flag was added after the SFTs were produced. [2] Segment files can be used as input to SFT-generation algorithms, e.g., lalapps_MakeSFTDAG. [3]
