Fig. 9

The subplot below plots the ground-truth curves obtained from multi-phase Rietveld refinements34 on the left and the corresponding Rietveld extracted weights in the right hand column, both in blue. The sparse-stretchedNMF extracted components and weights are overlaid in the respective panel in red.
