UNSCRAM - Harmonics Deconvolution using Multiple Film Packs

Abstract

The program UNSCRAM is used to deconvolute (unscramble) the intensities of individual reflections from multiple (harmonic overlapped) spots. It makes use of spots recorded on more than one film of a film pack and the fact that the scaling between films is a wavelength dependent function. In theory a six film pack could allow multiples with up to six components to be deconvoluted but in practice the method only gives reasonable results for doubles and possibly triples. The input is a set og .ge1/.ge2 files and a set of Victereen coefficients describing the inter film scaling function. The output is a set of lp corrected intensities which then need to be wavelength normalised.
