a Temperature dependence of 3D and 2D CDW intensities for YBCO6.67 at a axis compressions εxx= −0.7 % and −0.85 %. b 3D and 2D CDW intensities for YBCO6.55 at compressions of εxx= −0.57 % and −0.82 %. 2D CDW (3D CDW) intensities are determined from K-cuts (L-cuts). Error bars correspond to standard deviations of Lorentzian fits. Lines are guides to the eye. For a comparison of 2D and 3D intensities, see Supplementary Table 2. c Strain-temperature phase diagram of the 3D CDW intensity for YBCO6.67 with the Tc curve reproduced from ref. 28. Dashed orange lines mark the boundary of the 3D CDW phase. In the corresponding diagram for YBCO6.55 in (d) Tc(εxx) is estimated from the linear extrapolation down to the onset of the 3D phase43. Within the 3D CDW phase Tc(εxx) is based on the peak in the 3D CDW intensity.
