SAFiCF is a program for the Matlab environment that attempts to fit a set of crystal field (CF) parameters to inelastic neutron scattering (INS) data for rare earth or localised actinide compounds. It was written for Matlab 7 R14. It uses an implementation of the simulated annealing fitting algorithm due to Corana et. al. [Corana et al.(1987)Corana, Marchesi, Martini, and Ridella]. The block diagram for the program, labelling its constituent m-files is shown in figure 1. A brief theoretical description of crystal field excitations as observed in INS is given in section 2, and the program itself is described in detail in section 3, its usage in subsequent sections.
