The IACHEC aims to provide standards for high energy calibration and supervises cross calibration between different missions. Towards this end, the IACHEC usually convenes at an annual workshop but, due to these troubled COVID times, we instead hosted an online symposium over 2 days with 3 hour sessions each day. The purpose of the symposium is to present the work of IACHEC to the high-energy astrophysics community focused on the known calibration issues of individual missions, their cross-calibration, and how such problems may manifest in your data set and how they may be dealt with.
