Review of coupled betatron motion parametrizations and applications to strongly coupled lattices

Modeling and implementation of vertical excursion FFA in the Zgoubi ray-tracing code

“…In the linear approximation, the lattice functions must be computed with an adequate coupling parametrization, as explained in Ref. [23]. Fig.…”
