(a) Original and (b) pre-processed PDF profiles calculated from the hexagonal anhydrous rare-earth perchlorate Pr(ClO4)3 (Wickleder & Schäfer, 1999), with the crystal cell parameters a = b = 9.336 Å and c = 5.849 Å. (c) Weight fractions determined by the unfolding procedure applied to monoatomic crystal cells and fitted with a third-order bidimensional polynomial (surface in red) and (d) scatter plot showing the fit residuals. |
