摘要
MATISSE is the 2nd generation mid- infrared instrument designed to combine four VLTI telescopes in the L, M and N spectral bands. It's commissioning in Paranal is in progress since March 2018 and should continue until the middle of 2019. Here we report, in June 2018, the commissioning plan, tools and the preliminary results of the first two commissioning runs in MATISSE that show that the instrument is already fully operational with a sensitivity well beyond its specification. The quality of the measurements, as they obtained by the current observing procedures and delivered by the current pipeline are already good enough for a broad range of science observations. However, our results remain quite preliminary and they will be quite substantially improved by the work in progress in instrument calibration, observing procedures optimization and data processing updates.
