Maximum Entropy Spectroscopy — Dimes and Mesa

摘要: The direct “- f log f” and indirect “log entropy formulae have both been used in maximum spectroscopy. form is shown to be appropriate for finding the single “best” spectrum from incomplete data. should find an underlying probability distribution function, but not itself. Examples show how why liable give misleadingly sharp spectra. When true unusually sparse, as a simulation due Fougere, can reconstruct it more accurately than conservative form, other methods which deliberately seek lines are then likely do even better.
