Rietveld refinements of the MS10.5 solution at a 10 bar CO₂ pressure experimental data. From top-bottom: 90 K, 180 K, 245 K. The experimental data are shown in black, the calculated fit in red, and the residuals in grey below. All prominent peaks are labelled where C = clathrate peaks and I = hexagonal ice peaks. The larger residuals for some of the ice peaks are due to poor powder averaging due to the way the ice freezes inside the cell (preferred orientation) and the restricted cell rocking angle used to compensate for this during measurement.
