We held the 17th IACHEC meeting in Osaka, Japan. IACHEC is a consortium for international cross-calibration activities for X-ray detectors. More than 70 people attended from the US, Europe, China, Japan, etc. We are struggling to understand our own detectors by comparing own data with other detectors. Our recent major progress may include the understanding of the reflection on mirrors, which may resolve the long-standing discrepancy between the data from different detectors.
