N2 - Dickson and Taylor (1998) evaluated the NASVD (Noise Adjusted Singular Value Decomposition, Hovgaard, 1997) and MNF (Maximum Noise Fraction, Green et al., 1988; Lee et al., 1990) methods for reducing noise in gamma-ray spectra. They showed (Table 1) that the MNF method is far more effective at reducing noise than the NASVD method. This result is surprising, since my own experience and that of other researchers in this field (Hovgaard, personal communication) is that the two methods give similar results.
