国际高能校准天文学联合会（IACHEC）旨在提供高能校准标准，并监督不同X射线和伽马射线天文台之间的交叉校准。这一目标是通过工作组实现的，其中包括全球约40名天文学家。在这些小组中，IACHEC成员合作定义校准标准和程序。它们的范围主要是实用的：一组天文来源、数据和结果（最终发表在参考期刊上）将是对参考来源（“高能标准蜡烛”）进行协调和标准化分析的结果。我们在此简要介绍IACHEC进行的众多研究中的两项；从热信噪比1E0102.2‐7219中对O和Ne线通量进行了交叉校准分析，并在更高能量下对一个样品的簇温度和通量进行了比较研究。有关IACHEC活动的更详细情况可通过信息门户网站http://web.mit.edu/iachec/获得。
The International Astronomical Consortium for High‐Energy Calibration (IACHEC) aims to provide standards for high energy calibration and supervise cross‐calibration between different X‐ray and Gamma‐ray observatories. This goal is reached through Working Groups, involving around 40 astronomers worldwide. In these Groups, IACHEC members co‐operate to define calibration standards and procedures. Their scope is primarily a practical one: a set of astronomical sources, data and results (eventually published in refereed journals) will be the outcome of a co‐ordinated and standardized analysis of reference sources (“high‐energy standard candles”). We briefly describe here just two of the many studies undertaken by the IACHEC; a cross‐calibration analysis of O and Ne line fluxes from the thermal SNR 1E0102.2‐7219, and at higher energies a comparison study of a sample of cluster temperatures and fluxes. A more detailed picture of the activities of the IACHEC is available via the information portal at http://web.mit.edu/iachec/.
