Statistical determination of a morphological parameter in solar granulation: spatial distribution of granules.
Abstract
Summary. This article is concerned with the study of morphological properties of solar granulation, which are derived from two dimensional harmonic (power spectrum) analysis of the granule position. By use of a morphological model for the granulation, it is shown that the deviations in granules positions from an hexagonal reference structure (Benard Cells) have a gaussian distribution. A mathematical analysis demonstrates that the histograms of intergranular separation found in various literature may be interpreted as Rice-Nakagami distributions. The usefulness of such harmonic techniques is shown for research into ordered or quasi-periodic structures. Key words: solar granulation - harmonic analysis - morphology
