Description (last modified by Wenduo Zhou) (diff)
The parameters of TOF neutron peak profile for powder diffraction, such as Alph0, Alph1, Beta0, Beta1, and etc, can be refined by Back-to-back exponential peak profile parameters (Alpha, Beta, Sigma) of Bragg peaks, which are fitted individually by single peak fitting.
Enable RefinePowderInstrumentParameters() to refine instrument parameters, which are common to all Bragg peaks, from all peaks' peak parameters (alpha, beta, and sigma).
The algorithm to refine parameters against the model will include the Mantid minimizers and a Monte Carlo simulated annealing algorithm.
Delete the early version, RefinePowderInstrumentParameters, and rename RefinePowderInstrumentParameters2 to RefinePowderInstrumentParameters.
