  Bolometers are phonon mediated detectors used in particle physics experiments
to search for rare processes, such as neutrinoless double beta decay and dark
matter interactions. They feature an excellent energy resolution, which is a
few keV over an energy range extending from a few keV up to several MeV.
Nevertheless the resolution can be limited by the noise induced by vibrations
of the mechanical apparatus. In arrays of bolometers part of this noise is
correlated among different detectors and can be removed using a multichannel
decorrelation algorithm. In this paper we present a decorrelation method and
its application to data from the CUORICINO experiment, an array of 62 TeO2
bolometers.
