MATISSE is the new mid-infrared 4T beam combiner of the Very Large Telescope Interferometer. When fully commissioned, it will cover simultaneously L, M and N bands (3-12 microns in wavelength) with various spectroscopic resolutions. It is described on these pages.

MATISSE will be offered for normal operations starting in Period 103 (April-September 2019). In the meantime, we wish to demonstrate MATISSE new capabilities during Science Verification: ability to perform synthetic imaging via a dedicated imaging run, as well as updated limiting magnitudes (comapred to P103). All astronomers are invited to participate in this unique opportunity. 10 nights with the ATs will be devoted to the MATISSE Science Verification (SV) starting on April 26 2019.

Limiting magnitudes for image reconstruction (typical 10% precision in visibility and few degrees in phase closure):

  • L band coherent flux > 3 Jy for a 80 m baseline 
  • N band coherent flux > 20 Jy for a 80 m baseline 

Limiting magnitudes for model fitting:

  • L band coherent flux > 1 Jy 
  • N band coherent flux > 10 Jy

A call for SV proposals has been issued and the community is invited to submit proposals for the MATISSE SV using this proposal template and associated LaTeX file.

Imaging proposals should require observations with at least 2 of the 3 AT configurations Small, Medium and Large, with typically 6 calibrated observations per configuration. Execution of the observations will be optimized to fill the spatial frequency plane. The offered modes for SV are the same as for P103 (see this instrument page and the P103 MATISSE User manual).

The observations will be conducted in Service Mode by a dedicated team of ESO and MATISSE team astronomers and astronomers. The MATISSE SV team will be able to assist the successful PI¹s in the preparation and optimisation of the OBs on a best effort basis only. The collected data will be made available to the whole ESO user community.

GTO protected targets

The list of protected targets for the MATISSE Guaranteed Time Observations is available for P103. Observations of targets protected by the MATISSE GTO will not be accepted for SV.

WARNING: all (raw) data and calibrations are public immediately after the observations. There is no proprietary period nor earlier data release to the PIs. See the VLT Science Verification Policy and Procedures for more details.

General Information

An integral part of the commissioning of a new instrument at the VLT is the Science Verification phase. SV programmes include a set of typical scientific observations that should verify and demonstrate to the community the capabilities of the new instrument in the operational framework of the VLT Observatory.
