Paper Abstract

We perform ray-tracing simulations aimed at investigating the impact on the overall sensitivity of eROSITA of possible small errors in the mechanical shaping and positioning of the baffle rings above the mirror modules, to estimate to what extent they may contribute to degrade the efficiency of the baffle in eliminating the stray-light at the focal plane as well as to increase at the same time the vignetting, then reducing the effective area of the mirrors. Through the simulations we identify the ranges of acceptable tolerances.
