The system fulfills the GLAO promise and typically delivers an improvement by a factor of 2 in FWHM over the 4'×4' field of view of both Luci instruments, the two near-infrared imagers and multi-object spectrographs. In this paper, we report on the first on-sky results and analyze the performances based on the data collected so far. We also discuss adaptive optics procedures and the joint operations with Luci for science observations.ELETTRONICOenConference paper10.1117/12.22400942-s2.0-85001967730000387429700093https://www.spiedigitallibrary.org/conference-proceedings-of-spie/9909/1/First-on-sky-results-with-ARGOS-at-LBT/10.1117/12.2240094.short2016SPIE.9909E..36OFIS/05 - ASTRONOMIA E ASTROFISICAScienze Fisiche Settori ERC (ERC) di riferimento::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_17 Instrumentation – telescopes, detectors and techniques
