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.},
