We have developed a new technique to decouple the spectra of the host and the nucleus of type I AGNs using integral field spectroscopy (IFS) data. The technique is a simple extension of methods widely tested in 2D imaging. We present here the results from applying the technique to data taken with INTEGRAL at the 4.2 m WHT telescope on the Seyfert 1 radio‐galaxy 3C 120. We obtained, for the first time, a clean spectra of the host galaxy, without contamination from the nuclear source. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
