Paper Abstract

The Multi-conjugate Adaptive optics Demonstrator (MAD) has been developed by ESO, and installed at the Nasmyth focal plane of the Very Large Telescope Melipal at Cerro Paranal in Chile. Thanks to the multi-dimensional sensing and correction of MAD, the measurements recorded while the system is performing MCAO can be analyzed to retrieve the instantaneous characteristics of the turbulence seen from the focal plane of the telescope: seeing and turbulence profile. In this paper those measurements will be compared to the ones given by other tools at disposition at the focal plane: the guide probe and the active optics sensor, and at another location on the Paranal platform: DIMM and MASS.
