MATISSE - the four telescope VLTI instrument for the L, M, and N band

Summary

MATISSE is a four-telescope beam combination instrument operating in the L (between 3.2 and 3.9 μm), M (between 4.5 and 5.0 μm), and N (between 8.0 and 13.0 μm) bands. It operates in a spectroimaging mode, providing low, medium, and high spectral resolutions. MATISSE's angular resolution is set by the maximum separation of the telescopes and the field of view of the instrument. In a nutshell, MATISSE is able to resolve features as small as 3.5mas (milli-arcsecond) in the L-band and as small as 8mas in the N-band with the ATs, respectively 5mas and 12.5mas with the UTs.

The complete pre-requisites for MATISSE service mode observations and the up-to-date flux limits can be found on the instrument description page.

Publications based on data obtained with the MATISSE instrument should quote the following reference paper: Lopez, B., et al., An Overview of the MATISSE Instrument - Science, Concept and Current Status, 2014, The Messenger, Vol. 157, pp. 5-12
