BPM readbacks (green-circle) and quadrupole positions (red-cross) are also shown. The trajectory is fairly straight but does not necessarily follow the line established by the linac axis. This is due to the correlated BPM and quadrupole misalignments (random walk of the initial tunnel survey). position and angle at the undulator entrance is used to launch the electron beam down the center of the undulator, and the beam follows along near the center of the quadrupoles.
