Figure 4
Symmetric θ/θ scans described in Section 2.2 are compared on the same 2θ axis: (a) 1D pattern (black data) with gypsum powder diffraction intensities in PDF 04-015-8262 (red sticks) normalized to the same maximum; (b) 2D frame from the same sample mounting [Fig. 2(a)] with a mirror 2θ line at γ = 1.7° (green dashed line). |
