TL;DR: In this paper, the authors present the results of simulations in the framework of ESA-financed projects (SIMPOSiuM, ASPHEA, SPIRIT), in preparation of the ATHENA X-ray telescope, analyzing the effects of diffractive effects in an SPO mirror module, showing ray-tracing results including surface and profile defects of the reflective surfaces, and assessing the effective area and angular resolution degradation caused by alignment errors between SPO component segments.
