We propose a near-IR demonstration experiment with the two VLTI test siderostats (0.4 m) at Paranal, to be used both in wide-angle single-field and in narrow-angle dual-field astrometry. The specifica...
We use extensive seeing and low-atmosphere meteorological data obtained at the European Southern Observatory's La Silla complex in Chile, and at the proposed site of the Very Large Telescope at Cerro ...
The Generalized Seeing Monitor (GSM) has undertaken a campaign of measurement of the optical turbulent parameters : the Fried's parameter, the outer scale (L 0 ) and the isoplanatic patch, at Paranal,...
