Summary

The beta correction reduces the beta beat in the horizontal and vertical plane by a factor of 2 with remaining beats of $\approx$ 4 % and $\approx$ 3 %. Several vertical BBA measurements have been carried out revealing BPM offset distributions with standard deviations of $\approx$ 0.3 mm and variations of $\approx$ 10 % over several months. Horizontal BBA measurements taking into account path length effects in the determination of the difference orbit have just been started. The ``dynamic'' beam-based alignment based on the modulation of quadrupole currents, at $<$10 Hz [7], observing the modulation frequency component in the resulting orbit [8] is planned.
