Sublattice phase-resolved analysis revealing d-form factor DW. (A) Measured $Re{\tilde{O}}_x\left(\mathit{q}\right)$ from R(r) in Fig. 2A. The four DW peaks at Q and the DW Bragg-satellite peaks exist but are all poorly resolved. (B) $Re{\tilde{O}}_y\left(\mathit{q}\right)$ from Fig. 2A; again, the four DW peaks at Q and the DW Bragg-satellite peaks exist but are all poorly resolved. (C) Measured $Re{\tilde{O}}_x\left(\mathit{q}\right)+Re{\tilde{O}}_y\left(\mathit{q}\right)$ from A and B. The four DW peaks at Q are not detectable whereas the DW Bragg-satellite peaks are enhanced and well resolved. Compared to Fig. 1E, these are the expected phenomena of a d-form factor DW (with spatial disorder in ϕ_D). (D) Measured $Re{\tilde{O}}_x\left(\mathit{q}\right)-Re{\tilde{O}}_y\left(\mathit{q}\right)$ from A and B. The primary DW peaks at Q are strongly enhanced whereas the DW Bragg-satellite peaks have disappeared. Compared to Fig. 1F, these are once again the expected phenomena of a dFF-DW. (E) Measured $Re{\tilde{O}}_x\left(\mathit{q}\right)$ for an NaCCOC sample with p ∼ 12 ± 1%. The DW peaks at Q, and the DW Bragg-satellite peaks exist but are poorly resolved. (F) Measured $Re{\tilde{O}}_y\left(\mathit{q}\right)$ for NaCCOC. The DW peaks at Q, and the DW Bragg-satellite peaks exist but are poorly resolved. (G) Measured $Re{\tilde{O}}_x\left(\mathit{q}\right)+Re{\tilde{O}}_y\left(\mathit{q}\right)$ from E and F. The four DW peaks at Q are no longer detectable whereas the DW Bragg-satellite peaks are enhanced and well resolved. Importantly (modulo some phase noise) the Bragg-satellite peaks at inequivalent Q′ and Q′′ exhibit opposite sign. Compared to Fig. 1E, these are the expected phenomena of a dFF-DW. (H) Measured $Re{\tilde{O}}_x\left(\mathit{q}\right)-Re{\tilde{O}}_y\left(\mathit{q}\right)$ from E and F. The four DW peaks at Q are enhanced whereas the DW Bragg-satellite peaks have disappeared. Compared to Fig. 1F, these confirm the dFF-DW conclusion.
