JMMC - Service aux Utilisateurs du VLTI

As a new service of the JMMC, SUV (Service aux Utilisateurs du VLTI) provides, in four different sites (Nice, Grenoble, Paris, and Lyon), a complete support to the users of the 2nd generation VLTI instruments. This support consists of an individualized assistance (FAQ, answer to questions, face-to-face meetings) that covers the preparation of observing proposals and observations, and the GRAVITY and MATISSE data reduction. It also includes an assistance in the critical use of the JMMC model fitting and image reconstruction softwares.

SUV is coordinated by the Observatoire de la Côte d'Azur (OCA) in Nice, with three other local nodes in Paris (Observatoire de Paris), Grenoble (IPAG), and Lyon (Observatoire de Lyon):

- National coordinator (and local coordinator in Nice) : Alexis Matter (

- Local coordinator in Paris : Vincent Coudé du Foresto (

- Local coordinator in Grenoble : Jean-Charles Augereau (

- Local coordinator in Lyon : Eric Thiebaut (

A centralized helpdesk platform, hosted at OCA, collects all the user questions and requests for a face-to-face assistance in one of the four nodes. These questions and visit requests are then redirected to the relevant node. The SUV helpdesk (under construction) will be accessible through the JMMC webpage : (under construction).
