NAP: a tool for noise data analysis. Application to Virgo engineering runs

摘要

We present the noise analysis package library (NAP), a new tool to perform noise studies and data conditioning on the data produced by gravitational wave detectors. We describe its design and report the results of the application of parametric spectral estimation, whitening, line removal with adaptive notch filters and noise removal using a multicoherence procedure on the data taken by the Virgo interferometer during the C5 engineering run.
