Performance of the ESO AO system, Adonis, at La Silla 3.6m telescope

We report on the calibration and field test results obtained with the ESO/Meudon Adaptive Optics System, Adonis. This 7x7, 50cm subaperture system is now routinely in use at the ESO La Silla 3.6m telescope, offered to the astronomers together with two infrared cameras covering the 1-5 mu m wavelength range. The calibration activity summarized here has investigated the field performances achieved so far with Natural Guide Stars (NGS) using the either the Reticon or the EBCCD wavefront sensors.
