(a) Azimuthal integration of an averaged, background-subtracted detector signal. Locations of FCC and HCP lattice reflections are marked. (b) and (c) XCCA maps C(q1, q2, ϕ) measured at a distance to the nozzle of 598 µm, corresponding to Δt = 7.8 µs. (b) is sliced at the FCC (111) peak position (q1 = q(111)) and (c) at the FCC (200) position. Black dashed lines mark q1 = q2 correlations and black circles mark the expected peak positions assuming a perfect FCC crystal. The red dashed line in panel (b) marks the slice at [C(q_1 = q^{{\rm FCC}(111)},q_2 = q^{{\rm HCP}(100)},\phi = 90^{\circ})], as further discussed in Section 4[link].
