In-flight measurements of the optical axis and stray light of x-ray mirror assembly (XMA) on XRISM
The X-ray Mirror Assemblies (XMAs) on board the X-ray Imaging and Spectroscopy Mission (XRISM) underwent dedicated in-flight calibration during the early phase of the mission to ensure high-precision imaging and spectroscopic performance. This paper presents the in-flight determination of the Xtend-XMA optical axis and...
