      abstract     = {The development of ultra-low emittance storage rings, such
                      as the e+/e- Future Circular Collider (FCC-ee) with a
                      circumference of about 90 km, aims to achieve unprecedented
                      luminosity and beam size. One significant challenge is
                      correcting the optics, which becomes increasingly difficult
                      as we target lower emittances. In this paper, we investigate
                      optics correction methods to address these challenges. We
                      examined the impact of arc region magnet alignment errors in
                      the baseline optics for the FCC-ee lattice at Z energy. To
                      establish realistic alignment tolerances, we developed a
                      sequence of correction steps using the Python Accelerator
                      Toolbox (PyAT) to correct the lattice optics, achieve the
                      nominal emittance, Dynamic Aperture (DA), and in the end,
                      the design luminosity. The correction scheme has been
                      recently optimized and better machine performance
                      demonstrated. A comparison was conducted between two optics
                      correction approaches: Linear Optics from Closed Orbits
                      (LOCO) with phase advance + $\eta_x$ and coupling Resonance
                      Driving Terms (RDTs) + $\eta_y$. The latter method
                      demonstrated better performance in achieving the target
                      emittance and enhancing the DA.},
