Abstract
The highly resolved star images [ J. Opt. Soc. Am. A 9, 1937 ( 1992)] obtained with the 4-m Kitt Peak telescope have eluded explanation by conventional theory and yet are quite consistent with alternative predictions [ J. Opt. Soc. Am. A 9, 1937 ( 1992); J. Opt. Soc. Am. A 8, 346 ( 1991)] based on a smaller value of Lo. Tatarskii and Zavorotny [ J. Opt. Soc. Am. A 10, 2410 ( 1993)] claim that conventional theory also can predict the images, but one notes that they do not actually give specific predictions to support their claim. Based on a mistaken assumption about the magnitude of rms wave-height variations, they conclude that there is no difference between a core and a bright speckle. Thus they may not recognize the enormous significance of cores to Lo ground-based tracking and imaging at infrared wavelengths.
