A fast approximation to the complementary error function for use in fitting gamma-ray peaks

  • 1. Naval Research Lab., Washington, DC (USA)

Description

A fast approximation to the complementary error function has been programmed and tested for use in the peak-shape function for fitting peaks in gamma-ray spectra. The function was compared for speed and accuracy on the NRL ASC 7 computer to the mathematical library version of the complementary error function. The approximation has resulted in a 50% time savings in the computer program HYPERMET which was developed at NRL for automatic analysis of gamma-ray spectra from germanium detectors. (Auth.)
