Meeting Scope

Scientific results are now more than ever obtained as a synergy between observatories, and physical interpretation relies heavily on good instrumental cross-calibration knowledge, which is bounded by the resources devoted to calibration. The main goal of the IACHEC is to optimize the scientific value of current missions by improving the cross-calibration among existing instruments, creating new standards for analysis, promoting appropriate statistical methods for interpreting results, and optimizing calibration plans of future missions.
