Table 2. Parameters of the optics.
d: distance from the nominal source points (FEL-1/FEL-2); w:width; l:length; :grazing incidence angle. PM2a and SW have two coatings, each covering half the width of the mirror, and their position can be adjusted sideways to use one or the other coating. Orientation (H, V) refers to the deflection plane.
