Emma Y. Lenander et al.: Approximate resolution convolution function for fitting a dispersion gap measured on a triple-axis spectrometer #AnalyticConvolutionFunctions #GapSize #SpinWaves ... #IUCr https://journals.iucr.org/paper?S1600576726002049
An analytical convoluted gap function is presented for fitting either a linear or a quadratic dispersion gap in a constant-Q cut measured with a focused triple-axis spectrometer. It outperforms previous methods of fitting a gap, without requiring a full resolution convolution.
