Constructor Detail

PeakFinder

public PeakFinder(java.lang.String name,
                  int[] spectrum,
                  double sensitivity,
                  double width)

Creates new PeakFinder. Given a spectrum and search parameters, performs a digital filter peak search as specified in V. Hnatowicz et al in Comp Phys Comm 60 (1990) 111-125. Setting the sensitivity to a typical value of 3 gives a 3% chance for any peak found to be false.

Parameters:

spectrum - spectrum to be searched

sensitivity - larger numbers (typical=3) require better defined peaks

width - typical FWHM of peaks in spectrum
