In general. generation of charged-particle transfer maps for conventional iron-pole-piece dipole magnets to third and higher order requires a model for the midplane field profile and its transverse derivatives (soft-edge model) to high order and numerical integration of map coefficients. An exact treatment of the problem for a particular magnet requires use of measured magnetic data. ... https://www.jmannino.com/best-catch-University-of-Miami-The-U-iPhone-14-Plus-Clear-Case-p36265-quick-deal/
