Tools for noise characterization in Virgo

Abstract

Several software tools were used to perform on-line and of-line noise analysis as a support to commissioning activities to monitor the rate of glitches the occurrence of non stationary noise the presence of environmental contamination the behavior of narrow spectral features and the coherence with auxiliary channels. We report about the use of these tools to study the main sources of identified noise: broadband spectral lines and glitches. Plans for the upgrade of the tools will be presented for example for lines identification purpose to let the scientists in control room do noise characterization in an easier way. Show more
