* New lattice conditions in simulation: * MAPCLASS rematched optics with just sextupole components in QF1/QD0 (xsif lattice attached in text file) * Verical alignment data from Sugahara-san included * Immediate to-do tasks: * Understand differences between PLACET and Lucretia through AML transfer * Look and compare beam sigmas through lattice * Lucretia has integrated fringe field components in bends (FINT elements) not in PLACET- big effect? * Implement initial conditions from Kubo-san's ring simulations
