The seeing disc star images delivered by large (> 1 meter) telescopes typically measure about 1-arcsec across which, sadly, is about one or two orders of magnitude broader than would be delivered by diffraction-limited vers

Expressions are also developed for the average size and shape of individual speckles; these depend on the imaging wavelength, the atmospheric seeing parameters, and the telescop

To illustrate the crucial importance of average turbulence structure size on star image appearance, two wavefront realizations are generated, one where the outer scale is less than one meter, the other where the outer scale is three times larger. Instantaneous images are t

Nicolas Binaud,Stéphane Caro,Philippe Wengering these images are, for most people, unfriendly and unwelcome. In this chapter, therefore, we greatly simplify the mathematics by approximating star images by best-fitting Gaussians functions. A single Gaussian function is used to approximate core-only or halo-only images; two summed Gaussian func
