Paper Abstract

The Generalized Seeing Monitor is a new instrument for the monitoring of the atmospheric optical parameters (AOP) like the spatial-coherence outer scale L0, the seeing (epsilon) 0 and the isoplanatic angle (theta)0. This instrument, equipped with 4 identical modules, works like a Shack-Hartman and sensor and allows the analysis of the perturbed wavefront (observation of the angle-of-arrival fluctuations at four points. Several measurement campaigns have been done at different sites over the world: Cerro Paranal, La Silla, Cerro Pachon (Chile), Oukaimeden (Morocco) and Maydanak (Uzbekistan). The main results obtained for the AOP (L0, (epsilon) 0, (theta) 0) during these missions are presented and discussed. The whole of these measurements provides an important data bank allowing the analysis of the temporal variability of these parameters.
