I am Jelle de Plaa from SRON Netherlands Institute for Space Research and currently leading the data analysis and software group of the Astrophysics program. Our group has a lot of expertise and heritage in X-ray astronomy. We have been involved in missions like XMM-Newton RGS, Chandra LETG, and Hitomi. Currently, we are working with the XRISM and Athena X-IFU teams.

I am one of the people developing our X-ray spectral analysis tool SPEX, which is a tool optimised for high-resolution X-ray spectroscopy, which contains an atomic database, spectral models and fitting algorithms.
