IACHEC meetings
The IACHEC meets nominally every year. Meeting venues rotate among U.S.A, Europe and Japan. The next meeting is scheduled for April 27-29, 2009 in Japan. Meeting are open to contributions from the whole astronomical community. They are normally organized in plenary presentations sessions, where the calibration status of operational and future high-energy mission is reviewed, and splinter working groups sessions. Talks on the calibration impact of scientific results find their place in the program as well. Working Groups report the results of the work done in a final meeting session. The presentations and working group summaries held at the last IACHEC meeting (Ringberg, 2008) are available at the 3rd IACHEC Meeting web page.
