The JMMC softwares to prepare AMBER observations AMBER Workshop - LAOG - 9 Nov 2004

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 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 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
