Ray tracings at the exit slit plane at 1000.0 eV and 1000.1 eV: (a) with surface error data #1 on the grating, (b) with surface error data #2 on the grating, (c) with surface error data #2 on the plane mirror and surface error data #1 on the grating and (d) without surface error. The grating has a ruling density of 800 lines mm−1 at its center and is operated with cff 2.3. |
