Projections of Plasma Cloud Structures and their Spectra.

Abstract

We have established a relationship between the asymptotic spectral index of idealized piecewise-constant optically-thin radiating sources and their scans. For piecewise-constant clouds, where the one-dimensional asymptotic spectrum of the power is proportional to 1/k squared, we have shown that the asymptotic spectrum of the scan depends upon the character of the contour. We also apply the results to the interpretation of optical scans from two PLACES events. These are insufficiently resolved and their estimated spectral index of 2.5 is associated with a composite of effects and not the nonlinear dynamics of striation evolution. Keywords include: spectral index, power spectral density, plasma cloud scan, cloud contour.
