Hi, With regards to size/shape/distribution analysis of line profiles, the papers by Armstrong et al. (2004a,b,c) discusses a Bayesian/Maximum Entropy method, that determines these quantities from the line profile data. This can also resolve bimodal distributions from line profile data.
This method tests models for shape/size distribution and modal properties using Bayesian analysis. The maximum entropy components is a generalisation of the approach presented in A. Le Bail and D. Lou?r. J. Appl. Cryst. (1978). 11, 50-55. It preserves the positivity of the distribution, determines the most probable distribution give the line profile data, instrument profile and statistical noise.
