Scientific paper

A new power spectrum analysis of the Exosat soft (LE) and hard (ME) data of NGC 4051 was performed which enabled a chi squared model fitting technique to be used to fit different mathematical models to the resulting power spectra. Evidence for significant structure was found and the power spectra of the soft and hard components appear to be significantly different.
