The JMMC softwares to prepare AMBER observations

The JMMC softwares to prepare AMBER observations

AMBER Workshop - LAOG - 9 Nov 2004

The observing path from A to Z

The observing path from A to Z

Have a great idea that needs VLTI-AMBER !

Make sure it is feasible and useful Write a good ESO proposal Get observing time with AMBER Prepare and perform observations Analyze data Publish a great paper !!!

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
