Dear IFEFFIT experts: Is it possible to add a k^3 term in the phase for fitting to take into account anharmonic effect? The fitted coefficient will be proportional to the 3rd cumulant of Debye-Waller factor. I work with high-temperature high-pressure systems where anharmonic effect is not negligible. Thanks. Yuan Ping
