(a) Measured horizontal angular distribution of light from the UE56 for elliptical (black) and vertical linear (red) polarization at a photon energy of 700 eV at 0.1% bandwidth. (b) Corresponding calculated (with SRW code; Chubar & Elleaume, 1998) horizontal width of the full UE56 emission cone at 700 eV for the case of elliptical (black) and vertical linear (red) polarization. |
