Query: Scattered light noise characterisation at the Virgo interferometer with
  tvf-EMD adaptive algorithm   A methodology of adaptive time series analysis, based on Empirical Mode
Decomposition (EMD), and on its time varying version tvf-EMD has been applied
to strain data from the gravitational wave interferometer (IFO) Virgo in order
to characterise scattered light noise affecting the sensitivity of the IFO in
the detection frequency band. Data taken both during hardware injections, when
a part of the IFO is put in oscillation for detector characterisation purposes,
and during periods of science mode, when the IFO is fully locked and data are
used for the detection of gravitational waves, were analysed. The adaptive
nature of the EMD and tvf-EMD algorithms allows them to deal with nonlinear
non-stationary data and hence they are particularly suited to characterise
scattered light noise which is an intrinsically nonlinear and non-stationary
noise. Obtained results show that tvf-EMD algorithm allows to obtain more
precise results compared to the EMD algorithm, yielding higher
cross-correlation values with the auxiliary channels that are the culprits of
scattered light noise.
