Analysis of Field-Widened Interferometer Data by Least-Squares and Spectral Deconvolution Methods

摘要

Linear least-squares methods and the Jansson method of constrained nonlinear spectral deconvolution were used to analyze atmospheric emission spectra obtained in the Field-Widened Interferometer (FWI) experiment. The analysis provides estimates of line intensities and spectra of enhanced resolution. A conclusion of the study is that NO+ was not present in the auroral event observed by the FWI.
