JMMC’s missionJMMC’s mission JMMS is a network that gathers most of
the French interferometric expertise Its goal is to help VLTI users throughout
the process, except for what is taken care of by ESO or by the instruments’ team
This is true for both the French and European community
JMMC provides softwares and support

To calibrate the system’s performance, observations of a good calibrator are required just before or after the scientific target
