Gravitational Wave Detector Characterization
We are developing qualitative methods of examining data channels using audio
playback to facilitate classification of instrumental disturbances, and for
comparison with possible signals. We use sophisticated filtering and
spectrogram analysis tools, and do playback over high-quality audio equipment.
This has already led to some insights into the nature of LIGO glitches, into
mechanisms for non-linear pickup of acoustic noise, and suggested avenues of
further studies for possible burst event candidates.
