Implications of Turbulence Optical Parameters on HAR Techniques at Dome C
Published online by Cambridge University Press: 24 December 2009
Abstract
The HAR observing methods such as Adaptive Optics andInterferometery, require a better understanding of the behavior ofthe perturbed wavefronts, more exactly a better knowledge of theatmospheric turbulence model in addition to the associateparameters. This is very crucial for modeling the HAR techniques andparticularly for the evaluation of their performance. Indeed, it iswell-known that the performance of an AO system depends upon theseeing conditions, the outer scale, the isoplanatic angle and thecoherence time. A review of the site-testing instruments deployed atDome C will be given, their pertinence and their implications on HARtechniques will be discussed comparatively to the Paranal site.
