      abstract     = {The continuous spectrum required by the Q-EXAFS
                      monochromator can be realized by a Wiggler, Bending Magnet,
                      or tapered Undulator. For the AppAnaXAFS beamline, the
                      application of a 3-pole Wiggler is desired, if it can
                      provide a flux of $10^12$ photons on the sample. However,
                      3-pole Wiggler also have a high beam divergence and thus
                      large beam sizes. First considerations of a 3-pole Wiggler
                      setting showed beamsizes that exceeded the openings of the
                      mandatory safety shutters. In order to keep the losses due
                      to divergence as low as possible, a collimation of the beam
                      as close to the source as possible is crucial. Discussions
                      revealed two possible mirror locations: within the tunnel at
                      22m and outside the tunnel at 43m. The present documents
                      include scripts for calculating the x-ray beams for both
                      cases, including different mirror shapes, length, and
                      incident angles, as well as different energies of the
                      monochromator in order to evaluate the intensity at the
                      sample position. These scripts are part of the EURIZON
                      project and the main report is available under Task 4.6,
