Abstract
The centroid noise depends on the photo-electron flux, seeing conditions, and guide sensor specifications. The model for the photo-electron flux takes into consideration the guide star availability at different galactic latitudes, the atmospheric extinction, the optical losses at different filter bands, the detector quantum efficiency, the integration time and the number of stars sampled. A 7-layer atmospheric model was also developed to estimate the atmospheric decorrelation between the different guide sensors due to the 3.5deg field of view, to predict both correlated and decorrelated atmospheric tip/tilt components, and to determine the trade-offs of the guider servo loop.
