Here is the trick that allows one to include tune response (e. g. dQx/dK1 for some quadrupole) into orbit response fitting with Elegant. It's possible to find the exact solution for dQ/dK1 as a function of Twiss parameters at the beginning of the quadrupole (see the attached pdf for details). Using ...

I thought that for dynamic aperture the strongest effect comes from the field errors in bends. So if you have these SYSTEMATIC_MULTIPOLES and RANDOM_MULTIPOLES up to an arbitrary order in quadrupoles why not have them in dipoles? I'm quite new to dynamic aperture calculations. For electron machines ...

Thanks for the example!

Do you have plans to include higher order components (Kn, n>4) in CSBEND element?
